Industrial buildings need roofing that does more than just look good. They need something that performs exceptionally well in strength, safety, and lifespan. What’s more, this material has to endure tough conditions, like severe heat, heavy downpours, chemical contact, and even physical strain.

This is where the improved double-layer fiberglass-reinforced UPVC roof sheets come in. They are a new invention. This innovation is specifically designed for the toughest industrial requirements. For example, Jieli’s Model T940 perfectly illustrates how these modern panels mix physical power with fire safety and weather endurance, making them a much better choice than typical roofing options.

Key Features of Double-Layer Fiberglass-Reinforced UPVC Roof Sheets

The effectiveness of these enhanced roofing sheets starts with their very strong structural makeup.

Structural Composition and Design Enhancements

The fiberglass-reinforced UPVC roof sheet T940 is designed with a 4 mm double-layer fiberglass composition. By placing two fiberglass mesh layers close to the top and bottom, the extra support becomes easy to see from the outside. This gives plain proof of its inner power and guarantees extra toughness for the whole panel.

Load-Bearing and Impact Resistance Capabilities

The enhanced T940 model is built for serious industrial-level weight performance. With purlins set 1.6 m apart, the roof surface can hold 280 kg with barely any bending. Even better, it can securely hold four grown men, weighing 335 kg in total, without any danger of breaking or bending for good.

Its toughness is confirmed by very strict crash tests. It passed. A 1 kg steel ball dropped from 1.5 meters high leaves no cracks, harm, or marks at all. So, this strength guarantees lasting service, even when facing unexpected hits or environmental pressures.

Enhanced Fire Resistance Properties

Fire safety is extremely important for industrial roofs. Jieli’s fiberglass UPVC sheets are great at this. In the fire resistance test, a flame gun is used to burn for 20 seconds at maximum power, and the fire self-extinguishes once the flame is removed. They only get light burn marks on the surface, and their inner structure stays completely fine. Therefore, this makes them perfect for factories and warehouses where fire danger has to be kept very low.

Comparing Jieli’s Fiberglass UPVC Sheets with Conventional Options

Jieli’s double-layer fiberglass-reinforced UPVC roof sheets are obviously different from typical options in how they are built and how well they work.

Material Composition Differences That Matter

Regular UPVC sheets usually don’t have any inner support. Or they have one layer at most. On the other hand, Jieli’s T940 model has visible fiberglass mesh layers on both sides, which is a big difference. This special design, which only Jieli has in China, results directly in much better pulling strength and weight-holding ability.
