Products Description
This product is specially developed for the internal lining keel of aluminum alloy and steel structure sunrooms. It has low internal stress and minimal deformation due to temperature and humidity, solving the problems of cracking, bending, mold, and insect infestation caused by the thermal expansion and contraction of ordinary wood throughout the four seasons. It is suitable for villa courtyard sunrooms, terrace glass rooms, skylights, and landscape greenhouses, and can be used as the internal lining keel of steel structures, door and window reinforcement, roof support, and main material for wall lining.

Application Scenarios of Sunroom Lining
The company conducted a competitive advantage analysis to identify its strengths and weaknesses compared to its rivals.
Sunroom Roof Load-Bearing Lining Frame
The internal lining beams of the steel structure of the skylight roof withstand long-term exposure to sunlight, high temperatures, and temperature differences caused by rain and snow, without deformation or sagging, ensuring flat and leak-proof glass installation.
01
Sunroom Surrounding Wall Reinforcement Frame
The lining fills the steel structure columns, balancing thermal contraction and preventing cracking of wall finishes and enlarged glass gaps that lead to air leaks.
02
Sunroom Door and Window Opening Reinforced Timber
Reinforcement of stress-concentrated areas in doors and windows offsets thermal expansion stress from sun exposure, ensuring they remain secure even after long-term opening and closing and that the sealant does not crack.
03
Courtyard Greenhouse/Greenhouse Skylight Frame
A complete support frame for small landscape sunrooms, moisture-proof and mildew-proof, suitable for the high humidity environment of indoor plants.
04
Sunroom Project Bulk Supply Main Materials
Stable dimensions and uniform performance, compatible with standardized mass production in sunroom manufacturing plants, resulting in a low return rate with long-term bulk supply.
05
Highly Stable Materials and Core Performance Advantages
Selected high-density veneer with minimal knots and consistent grain, employing multiple constant-temperature stress-release processes, combined with weather-resistant and waterproof structural adhesive, suitable for the high temperature, high humidity, and large temperature difference conditions of sunrooms.
Extremely Low Coefficient of Expansion/Contraction, No Cracking in Temperature Variation Environments: Long-term curing after molding eliminates internal stress, resulting in minimal shrinkage under summer sun exposure and winter low temperatures, preventing strain on the glass and sealant.
Waterproof and Moisture-proof, Suitable for Both Indoor and Outdoor Use, No Mold Growth: Balanced moisture content control prevents rainwater penetration and swelling in high-humidity indoor environments, eliminating blackening and mold growth.
High Bending Resistance, No Sagging of the Top Surface: Multi-layered, high-pressure pressing with consistent grain allows for long-term support of the glass and insulation layer's weight without permanent bending deformation.
Strong Nail Holding Power, Secure Hardware Fixing: Dense and uniform veneer prevents chipping during nailing and screwing, ensuring a strong and durable connection between the sunroom's aluminum frame and veneer.
Insect-proof and weather-resistant, durable for long-term outdoor use. The sealed laminated structure prevents insects from entering and is not easily powdered or aged by ultraviolet radiation, greatly reducing the need for later maintenance.
Production Process and Exquisite Craftsmanship for Sunrooms
The entire process revolves around high-temperature resistance, low deformation, and waterproofing/moisture-proofing, with meticulous control over dimensional stability at every stage.
Screening of Uniform Veneers with Fewer Knots
Removing diagonal grains, large knots, and loose boards to avoid localized stress concentration that could lead to cracking later.
1
>>
Gradient-Balanced Constant-Temperature Drying
Segmented, slow dehydration to unify the moisture content of the entire batch, minimizing the difference between wet and dry shrinkage.
2
>>
Uniform Application of Weather-Resistant Waterproof Adhesive
Using a special outdoor temperature-resistant waterproof adhesive that does not soften at high temperatures or crack at low temperatures, ensuring permanent bonding between layers without delamination.
3
>>
High-Pressure Hot Pressing with Grain-Side Balance
Uniform grain arrangement disperses thermal expansion stress, resulting in a dense, gapless surface that blocks moisture penetration.
4
>>
Long-Term Constant-Temperature Stress Curing
Multi-day static curing releases all pressing stress, eliminating the risk of slow deformation after the finished product leaves the factory.
5
>>
Four-Sided Fine Sanding and Waterproof End Sealing
The smooth surface facilitates bonding with aluminum, and the sealed waterproof ends prevent water absorption and deformation of the wood ends.
