As a high-quality building material, metal corrugated composite board has many significant advantages. The following is a detailed explanation of its advantages:
1. High strength and excellent load-bearing capacity: Metal corrugated composite panels combine the high strength of metal with the stability of corrugated structures, giving them excellent compressive, bending, and impact resistance.
2. Excellent waterproof and moisture-proof performance: The structural design of metal materials and corrugated composite panels has excellent waterproof performance, which can effectively prevent moisture infiltration.
3. Environmental protection and energy conservation: All materials are recyclable and there is no construction waste.
4. Easy construction and high efficiency: The metal corrugated composite board adopts systematic design and factory processing, which can be customized according to actual needs and is easy to install.

Quick construction: The roof panels are fixed by lap joint machinery, and the TPO waterproofing membrane is prefabricated in the factory. The lap joint is 100% hot air welded, which improves efficiency by 50% compared to similar roofs.

Lightweight insulation: The core material is made of lightweight insulation material, rock wool -120K, with a thermal conductivity of 0.040. The comprehensive square unit weight of the product is about 15-30Kg/m2.

Architectural effect: The inner and outer color coated steel plates are coated with different coatings such as PE/SMP/HDP/PVDF according to the environment to achieve different architectural effects. Combined with AZM coating, it can provide a warranty of over 30 years.

High strength assembly: Four wave corrugated, increases the resistance moment of the roof panel, and can save the amount of steel used for purlins in the design. 100% factory prefabrication contributes to low-carbon and energy-saving indicators.

First level waterproofing: The factory prefabricated TPO waterproofing membrane fully meets the national standard requirements for first level waterproofing.

Explosion venting wall panel is a new type of board that has the functions of load-bearing, insulation, sound insulation, fire prevention, and explosion venting. It has the characteristics of lightweight, high strength, and factory production, and is suitable for production plants that require explosion venting. It will not cause secondary damage during explosion.

The TPO prefabricated integrated flexible roof system uses TPO coil and profiled steel plate as the surface layer, high-strength water rock cotton as the core material, bonded by high-strength adhesive, and formed into a self-supporting integrated composite board through advanced continuous line hot pressing composite in the factory. Compared with the original flexible roof scheme, the waterproof surface layer, insulation layer, and DECK bottom steel plate base layer installed in layers are integrated to achieve fully prefabricated production of finished products in the factory. The TPO flexible roof system integrates the advantages of various materials, reflecting the design concept of "integrating the benefits of gold and stone, and achieving the beauty of both rigidity and flexibility".
