Steel Roof

The steel roof has high overall structural strength and excellent drainage performance, making it suitable for roofs of all sizes and shapes. The roof panels require no nail holes, ensuring superior corrosion resistance. In regions with large temperature variations, the panels’ outstanding thermal expansion and contraction capacity effectively prevents cracking and leakage caused by temperature changes.

Building Span:50m – 200m

Building Height:20m – 70m

Roof materials: AMMB, PPGI, insulation layer

Temperature: -40 ° -50 ° C

Service Life:50–70 years

steel roof

As a new type of building material system, Steel roof is widely used in various applications, including stadium roofs, museum roofs, airport terminals, railway station platforms, sports arena roofs, and the roofs of various buildings.

steel roof design

The design of a steel roof should be based on the specific project application, taking into account factors such as structural strength, waterproof performance, and thermal insulation. Prefabricated steel structures are often used as the load-bearing components of steel roofs. Depending on the span and spatial requirements, an appropriate structural form should be selected. For large-span metal roofs, a grid-truss structure is recommended due to its high structural strength and suitability for long-distance transportation.
Henan Gefan Building Materials Co., Ltd. adopts BIM modeling technology to closely integrate prefabricated steel structures with metal roofing systems, improving model accuracy and reducing construction costs.

steel roof production

The steel roofing system typically includes prefabricated steel components, purlins, bracing, and roof panels. We use laser cutting machines to process raw materials, ensuring precision while improving production efficiency. Automated welding robots guarantee that the processing quality meets strength requirements. The intelligent sandwich panel production line enables stable and efficient production throughout all stages — from raw material handling and processing to cutting and packaging. Quality inspection and component coding ensure product reliability and greatly enhance installation efficiency at the project site.

steel roof transportation

Henan Gefan Building Materials Co., Ltd. has an experienced team of engineers and international logistics professionals who efficiently coordinate material packaging and container loading to minimize volume and reduce sea freight costs. Prefabricated steel components are packed using standard steel frames, while roof panels are covered with protective plastic film to ensure the materials remain undamaged during marine transportation.

steel roof installation

The installation of a steel roof follows three key steps. First, position and secure the embedded parts of the prefabricated steel components to the concrete foundation. Next, install the steel components according to the detailed installation drawings provided by our company, following the unique component codes that greatly improve installation efficiency. Finally, install the roof panels and apply proper waterproofing measures. As a professional manufacturer of steel roofing systems, Henan Gefan Building Materials Co., Ltd. has a highly experienced overseas construction team. We can dispatch engineers to assist with on-site installation or provide training for local installation teams. Send us your project requirements to receive a customized solution and quotation.
