Specifications of metal roofing

　　Metal RoofSpecifications

　　A metal roof is made of metal, combining a structural layer and a waterproof layer. If acceptance is not conducted during the installation process, it is easy to encounter leakage issues. Today, let's take a look at the specifications of metal roofs.

　　Metal RoofMaterial Requirements:

　　Variety Specifications: Color-coated steel plates: Irregularly shaped structural steel plates on the roof can be formed through rolling processing, with widths mainly of 600mm, 620mm, 650mm, 720mm, 750mm, 900mm, etc. The length is based on the manufacturer's design drawings, with on-site processing and forming up to 48 meters, while the standard length is limited by transportation. Insulation materials: The materials for the insulation layer should meet the requirements of the teaching design in terms of variety, thermal conductivity, thickness, and density. Common insulation layers include glass wool; self-extinguishing polystyrene or polyurethane foam. Purlins and tie rods: Purlins and tie rods are the supporting management system for metal structure roof panels. Fasteners: Mainly include economical expansion bolts, rivets, self-tapping screws, plates, washers, nuts, etc., for connecting various structural designs and installation work between panels and frames.

　　Quality Requirements: After entering the factory, the appearance of color-coated steel plates should be inspected. The edges should be neat, the surface smooth, the color uniform, and the appearance tidy, without defects such as distortion, warping, peeling, or rust. The variety, thermal conductivity, thickness, density, factory qualification certificate, and test report of insulation materials must meet design requirements. Purines and rebar: The main materials are C-shaped or Z-shaped cold-rolled galvanized steel plates. The thickness and rigidity of the section steel must meet the requirements of the teaching design. Fasteners: Expansion bolts, rivets, self-tapping screws, plates, washers, nuts, etc., for various teaching designs and installation connections between panels and frames need to be galvanized to prevent corrosion.

　　Metal RoofMain Tools: Manual automatic cutting machine, electric edge-locking machine, electric tool wrench, positioning wrench, electric welding machine, portable electric drill, riveting machine, special stapler, paper cutter, marble saw, pliers, rubber hammer, steel wire, steel rope, lifting machinery equipment.　　

　　Conditions for Metal Roof Work: Before the installation of the metal roof color steel plate project, technical management personnel should thoroughly familiarize themselves with the manufacturer's drawings and carefully study the technical development measures, quality requirements, and product protection for the construction operators. After the section steel and various accessories arrive on site, carefully check their detailed design dimensions, specifications, quantities, and whether they are consistent with the installation construction drawings. The installation of the roof steel structure has been completed and accepted. The scaffolding for the roof panel installation is finished.
