What are the classifications and advantages of roofing panels

According to the sandwich material can be divided into: polyurethane roof board, rock wool roof board, polyurethane rock wool roof board.

According to the connection method can be divided into: dark nail roof board and nail roof board, in the installation of the overlap, the nail will be outside, we usually call it the nail type, the nail is not in the leak outside called it hidden.

1. Dark nail roof panel

The lapping mode of three corrugated roof panels is dark nail lapping. The hidden roof board is connected by dark nails, hidden screws, the board surface is closely bonded, and the unique anti-sink design effectively prevents rainwater penetration and avoids the phenomenon of cold bridge; The 40mm crest height design improves the bearing capacity of the roof panel, reduces the use of roof purlins, enhances the load capacity, and balances the flow of water. While ensuring the thermal insulation effect of the building, it effectively reduces the construction cost of customers, and has the characteristics of energy saving and thermal insulation, flame retardant and fire prevention, airtight and sound insulation, waterproof and rust prevention, beautiful and economic.

2. Nail roof panel

The lapping mode of four corrugated roofing panels is open nail lapping. The four-wave lapping roofing plate has corrosion resistance, and the inner plate can be replaced by aluminum foil to improve the product's high temperature and corrosion resistance. Solid surface, four waves of corrugated, increase the robustness of the surface. The lap joint is reasonable, and the bevel design at the small edge of the lap joint is simple and reasonable. Beautiful economy, beautiful appearance, rich color; Reduce material loss. The construction is fast, the design of the joint is simple and the construction is convenient.

Advantage

The corrugated design of the roof panel is not only beautiful, but also can distinguish the roof panel from the wall panel. The unique corrugated design can also drain rainwater and prevent the roof from collecting water.

The fire performance of polyurethane sandwich board: excellent fire performance, polyurethane material can meet the high fire performance requirements of building insulation materials, effectively prevent the spread of fire, that is, B1 or B2 flame retardant standards.

Most of the roofing of the workshop is the choice of polyurethane roofing board, because the insulation performance of polyurethane board is better; The insulation performance of pure polyurethane is higher than that of polyurethane edge sealing, and the fire performance of polyurethane edge sealing is higher than that of pure polyurethane composite board

Polyurethane sandwich board is often used as an energy-saving material in modern engineering. Because the polyurethane sandwich board is beautiful in appearance, the overall effect is good, it sets load bearing, heat preservation, fire prevention, waterproof in one, and no need for secondary decoration, quick and convenient installation, short construction period, good comprehensive benefits, has a good cost-effective advantage, is a widely used board.
