Galvanized corrugated metal roofing sheet is a high-performance and multifunctional building material widely used in industrial, commercial, and civil construction fields. The following are the installation requirements for galvanized corrugated metal roofing sheets:

1. Grassroots requirements

The roof base layer should meet the design requirements to ensure that the main structure and supporting structure are accepted as qualified. The base layer should be flat, clean, and free of oil stains, dust, and other debris to ensure a tight fit between the roof panel and the base layer.

2. Layout and laying

According to the construction drawings, deepen the layout design to ensure that the laying sequence and overlapping method of galvanized corrugated metal roofing sheets meet the design requirements. During the laying process, the laying should be carried out according to the technical requirements of the metal plate shape and the layout diagram of the detailed design, ensuring that the plate joints are aligned and flat.

3. Fixed method

Galvanized corrugated metal roofing sheets should be fixed with specialized fasteners, and the position and quantity of the fasteners should meet the design requirements. For high corrugated roof panels, fixed brackets should be installed, which should match the waveform of the profiled steel plate to ensure the stability of the roof panel. Fixed components should use self tapping screws, rivets and other connecting components, which should be hot-dip galvanized to prevent moisture and rust. At the same time, sealant should be applied around the connectors to prevent roof leakage.

4. Overlapping and sealing

The overlapping method of roof panels should meet the design requirements, generally using overlapping connections or fastener connections. Sealing strips or waterstops should be installed at the overlap to ensure the sealing of the overlap. During the laying process, a full-length sealing strip should be placed between the longitudinal overlaps of the two boards, and two sealing strips should be placed at the ends. The sealing strips should be continuous and uninterrupted. After tightening the bolts, the joint between the two plates should be sealed tightly with acrylic or silicone sealant to ensure the waterproof performance of the joint.

5. Detail construction processing

The gutters, eaves gutters and other parts should be made of metal sheets, and the length of the metal sheets extending into the roof should meet the design requirements to ensure the waterproof performance of the gutters and eaves gutters. The insulation layer of the ridge, eaves, gable and other parts should be integrated with the roof insulation layer to ensure the overall insulation performance of the galvanized corrugated metal roofing sheet. The overlap width between the flashing board and the metal sheet should meet the requirements of different board types to ensure the sealing of the flashing area.

6. Construction precautions

During the laying process, temporary fixing measures should be taken for the metal plate to ensure its flatness and stability. During the construction period, protective measures should be taken for the installed metal plates to avoid damage. In case of strong winds or adverse weather conditions, temporary fixing and protective measures should be taken. After the construction is completed, observation after rain, overall or partial watering test, and water storage test should be conducted to ensure the waterproof performance of the roof.
In summary, the installation requirements for galvanized corrugated metal roofing sheets are strict and meticulous, requiring construction personnel to possess professional skills and a rigorous attitude. Following the above installation requirements can ensure the installation quality and effectiveness of the roof panels.
