Frequently asked
questions.

WPC is wood-plastic composite: a blend of wood fibres, polymer and additives. SungemWPC uses different profiles for decking, fencing, cladding and architectural louvers. Composition and intended use vary by product; confirm the specification for the selected model.

The outdoor range includes composite decking, fencing, wall cladding, railing and pergola profiles, louvers and compatible installation accessories. Share your product list so the team can coordinate the supply scope.

Capped boards add an outer protective layer to the composite core. Uncapped boards expose the composite material at the surface. Compare the selected profile’s care instructions, test documentation and warranty rather than assuming all boards in either category perform the same.

Compare appearance, maintenance, installation and whole-project cost. Composite has a finished surface and does not need the regular painting or staining associated with timber, but still needs cleaning and correct installation. Performance depends on the selected product and site conditions.

Service life depends on the profile, installation, exposure and care. Confirm the selected product’s specification and written warranty instead of assuming one lifespan applies to every composite product.

Review the current colour card and model-specific options, then compare physical samples under your project lighting. Similar colour names across decking, fencing, cladding and accessories may look different because their textures and profiles reflect light differently. Confirm availability before ordering.

Interior products may use PVC or bamboo-fibre constructions depending on the model. They are not interchangeable with outdoor WPC. Confirm material, application and current availability against the approved specification.

Share the room type, desired visual rhythm, dimensions, finish direction and installation conditions. SungemWPC will help identify suitable profiles for review.

Shield Series has a protective cap for projects prioritising surface protection. Natural Series offers deeper wood-grain character, while Essential Series is a practical option for value-focused projects. Match the exact model to traffic, exposure, desired finish and maintenance expectations; series names alone do not establish suitability.

Composite decking is intended for outdoor use and resists moisture, but does not replace a waterproofing system. Plan drainage and ventilation and follow the selected profile’s installation guidance.

A textured finish does not make a deck slip-proof. Surface condition, water, debris and maintenance affect grip. For a wet-area or commercial project, request slip-test information for the selected model and match it to your project requirements.

Decking can be considered for poolside applications when the selected profile, drainage, clearances and fixing system suit the project. Review wet-area performance and the installation requirements before choosing a board.

Compatible decking profiles use clips and coordinated accessories to achieve a concealed-fixing appearance. Confirm the selected board’s groove, supporting joists, perimeter details and current installation guidance before ordering.

The recommended joist spacing depends on the decking profile and application requirements. SungemWPC provides technical installation recommendations to ensure proper support, stability and long-term performance.

Composite decking can be cut with appropriate woodworking tools. Follow the product’s installation guidance and the tool manufacturer’s instructions, including suitable blades, dust control and personal protection.

Shield has a protective cap for projects prioritising surface protection. Natural has a more pronounced 3D wood-grain texture; Essential offers a simpler brushed finish and practical value. Choose the exact system against your design, exposure and maintenance needs.

Colours, textures and post combinations vary by model and market. Essential and Natural can be configured with black aluminium or compatible colour-matched WPC posts; Shield is primarily paired with black aluminium posts. Confirm final availability before specification.

Composite fencing is moisture resistant and designed for outdoor use, but it should not be described as fully waterproof. Correct drainage, clearances and installation details remain important for long-term performance.

Confirm local planning, permit and building-code requirements. Plan the fence line, verify the substrate and post positions, and use the installation instructions and safety equipment specified for the selected system.

Yes. Compatible systems can use base-plate fixing on suitable hard ground or concrete-set posts on soft ground. Site conditions, engineering requirements and local building codes determine the final method.

The current 162Q20 planning specification uses a 1840 mm centre-to-centre distance between adjacent posts. Confirm the latest approved installation drawing before construction.

After posts are installed and levelled, the bottom rail is secured, boards are stacked into the post grooves, and the top rail and finishing components are fitted. The current 162Q20 planning specification uses up to 11 boards per standard panel; verify the final project drawing before installation.

The current 162Q20 planning configuration can combine fence boards with a compatible PVC or aluminium screen. Screen type, support rail and board count must match the approved system drawing.

A system may suit poolside screening, but a pool safety barrier requires a separate assessment of the complete assembly against local requirements. Confirm moisture exposure, wind loads, heights, openings, gates and installation details with your project professional.

Shield Series adds a protective co-extruded cap and architectural profile options. Natural Series offers traditional WPC with wood-grain character for value-led or residential designs. Compare the selected profiles, supporting system and project requirements before specifying.

Yes. Depending on the profile and project design, SungemWPC cladding can be installed horizontally or vertically. The subframe direction, fixing method, ventilation gap and board spacing should follow the relevant installation guide.

SungemWPC cladding is primarily designed as an exterior finish and protective façade system. Dedicated insulation should be specified separately when thermal performance is required.

Yes. Combining woodgrain, fluted or slatted directions can create contrast and depth. Confirm colour availability, trim compatibility and installation details before ordering.

SungemWPC cladding is designed to resist moisture and outdoor weathering, but it is not the waterproofing layer for the building. Use a suitable substrate, membrane, ventilated cavity and flashing details where required.

Many profiles position fixings in concealed grooves or beneath the next board. Exposed edges, corners and finishing points may use coordinated screws or trims, depending on the selected system.

A suitable subframe provides a stable fixing base and maintains the cavity behind the boards. Ventilation helps manage moisture and allows the wall assembly to function as designed. Follow the selected system’s requirements for support, clearances and movement.

Yes. Plan suitable subframe support and compatible trims around openings, external corners and exposed board ends to create a complete, well-finished façade.

Louvers are architectural profiles for screening, shading, façade details and decorative outdoor features. A pergola is a complete structure with posts, supports and roof elements. Louvers may form part of a design but do not constitute a complete pergola system.

Shield Series has an upgraded protective surface. Essential Series is a practical first-generation WPC option for decorative screening. Confirm the profile, supports, exposure and care requirements for the proposed application.

Yes. Combining profiles, sizes, colours or orientations can create depth and contrast. Plan the layout, support details, spacing and transitions before ordering, and confirm the selected items are compatible for the same application.

No. Moisture-resistant profiles do not make an open arrangement rainproof. A rainproof design needs a suitable roof covering, drainage, supporting construction and review of any additional loads.

Yes, subject to the selected profile, supporting structure and installation guide. The support direction, fixing method, louver spacing and expansion allowance must be designed for the chosen orientation and application.

Do not assume a WPC profile is a stand-alone load-bearing member. Confirm the complete load path, reinforcement, supports and connections against the applicable product information and project calculations with a qualified professional.

Installation requires a stable, level and suitable supporting frame together with the correct fixing accessories. The exact method depends on the louver model, orientation, project design and local conditions. Please follow the product-specific installation guide before starting work.

The railing collection includes ST80K45, ST60K40A, ST90K40, ST60K60 and ST90K90. Compare their shapes on the railing page and quote the model code when requesting current drawings or a quotation.

The pergola collection includes ST100K60, ST160K80, ST200K100 and ST150K150. Ask for the current profile drawings to confirm dimensions and intended use, and review the full supporting structure separately.

The product pages show individual WPC profiles. Your quotation should identify the included profiles, posts, reinforcement, connectors, caps, fixings and quantities. Do not infer a complete kit from a product photograph.

Suitability must be confirmed for the complete proposed assembly and the project requirements. Have your project professional review the structure, fixings, loads, height and openings before specifying a safety barrier.

Request the current drawing for the selected model and the applicable assembly details from SungemWPC. Confirm lengths, tolerances, reinforcement and fixing requirements for the proposed use before ordering.

Include your preferred arrangement in the enquiry. Freestanding and building-attached designs have different support and connection conditions; feasibility must be reviewed for the site and selected assembly.

No exterior material is maintenance free. Remove leaves and debris, rinse normal dirt and use a soft brush with mild soapy water where the care guide permits. Keep drainage and ventilation clear, and inspect fixings and clearances. Avoid strong solvents and abrasive cleaners; follow the selected model’s care instructions.

SungemWPC products are supplied with a finished surface and do not require routine painting, staining or sealing. Select your colour before installation and check the model’s care guidance before applying any coating.

Outdoor exposure can cause colour adjustment; the extent depends on the model, colour and climate. Tonal variation can also occur between batches. Approve physical samples, order the project quantity together where possible and follow the product guidance for mixing boards during installation.

WPC profiles can move with temperature changes. Follow the selected system’s specified clearances and fixing method. Do not force profiles tightly against a frame or adjacent materials, or use one universal gap for every product.

A protective surface can help with everyday marks and cleaning, but no exterior finish is completely scratch-proof. Avoid sharp or abrasive objects, clean spills promptly and follow the selected model’s care instructions.

No universal compatibility is implied. A hidden clip must match the board groove, fixing method and supporting joist. Send the decking model code and planned support arrangement for confirmation.

A fascia is a flat finishing board used in a perimeter detail. An L trim has an angled section that can finish an edge or corner. The appropriate component depends on the profile and the approved installation detail.

The supplied product range groups SG49K49A, SG49K49B and SG46K39 with SG219K26. SG49K49A is identified as an external corner. Confirm the position and fixing detail for each selected trim with SungemWPC.

Provide the main profile code, layout, dimensions and edge or corner details. Quantities should be worked out from the agreed fixing and finishing schedule, including cuts and the installation allowance for your project.

Ask for an itemised quotation identifying each included component. Photographs showing multiple pieces are product references and do not define the contents or quantity of a supplied pack.

Available components can include profile-compatible screws or clips, subframe elements, starter trims, corner trims and edge trims. The exact schedule is confirmed against the selected board model.

Yes. Request samples of the profiles and finishes you are considering to review colour, texture, cross-section and dimensions. Share your application and destination so the team can confirm the sample selection and arrangements.

Custom colours, profiles, lengths, packaging and coordinated product selections can be reviewed for distributor or project orders. Provide drawings, an approved colour reference, quantities and market requirements. Feasibility, minimum quantities and lead time are confirmed for the specific request.

Board length depends on the selected profile, project quantity and production requirements. Confirm standard and custom length options with the SungemWPC team before quotation.

Lead time depends on the selected profile, colour, quantity, accessories and production schedule. Share the product list and destination for a confirmed production lead time.

Send the project location, application, layout and dimensions, profile codes, colours, quantities and target date. Include the support or substrate plan, stairs, corners and openings. For pergolas, also identify roof coverings, lighting and other loads, and provide structural drawings where available.

Tell us which boards, profiles and accessories you need. Our team can review the sourcing, compatibility, packing and shipping options for your proposed order.

SungemWPC coordinates manufacturing, product discussions, samples and order planning with distributors and project buyers. Compare suppliers on quality responsibilities, communication, product documentation and the ability to coordinate your proposed order, as well as price.

Request the written warranty for the exact model, market and intended use before purchase. Review coverage, exclusions, storage, installation and maintenance conditions, the stated term and the claim process. Do not assume one warranty covers every product or application.

Request the current specification and installation details for the selected model. If a project requires a specific test or certification, provide the standard, application and market so the team can confirm relevant documentation and its scope. Review supporting frames, perimeter details and local requirements before installation.

The useful questions are where the wood fibre and polymer come from, how much recycled content the specific product contains, and how it performs over its working life. Ask for product-specific composition and supporting documentation rather than relying on a general environmental label.

Collection and processing options depend on the formulation, condition of the boards and facilities available in your region. Ask us about the selected product and check with a local specialist before planning disposal or recycling. Do not assume acceptance through household recycling.

This needs to be assessed against the particular formulation, intended use and applicable testing. Tell us which substance or emissions requirements your project must meet so we can discuss relevant product documentation.

Credit eligibility depends on the project, rating-system version and the documents accepted by your assessor. We can discuss the available product information with your specification team; using a product does not itself guarantee a credit.

Share the product specification and recycled-content target with our team. Material availability, performance requirements and supporting evidence need to be reviewed together before a formulation or percentage is agreed.
