1.What is the core method for installing galvanized coils?
Core method: Mechanical fixing
Self-tapping screws or blind rivets are used to directly fix the sheet metal to the keel or structure.
Screws are usually equipped with sealing washers to prevent water leakage and compensate for thermal expansion and contraction.
2.What is the process flow for installing galvanized coils?
Laying out and measuring.
Cutting: Use a circular saw or angle grinder to cut; the cut is simple (just apply anti-rust paint).
Drilling: Drill holes at the predetermined locations.
Securing: Secure the boards with screws.
Sealing: Seal the seams and overlaps with neutral silicone sealant.
3.What are the advantages of installing galvanized coils?
High speed: Suitable for large-scale construction.
Low cost: Low labor and tool costs.
Available technical resources: Construction workers are easy to find.
4.What are the difficulties and risks in installing galvanized coils?
The key lies in waterproofing; the order of overlapping and the quality of the sealant are crucial.
Proper corrosion protection is essential at the cuts and drilled areas; otherwise, rust will begin to appear there.
5.What is the installation process for titanium-zinc coils?
System Design: The entire system's fixing points, expansion joints, and drainage paths are pre-designed.
Pre-treatment/Pre-forming: Panels are often pre-fabricated into the required shapes in the factory or on-site according to the design.
Fixed Support Installation: Specialized aluminum alloy or stainless steel fixed supports are first installed on the base layer.
Panel Positioning and Engagement: Titanium-zinc sheets are snapped into the supports, and then the vertical edges are folded and engaged using specialized hand tools.
Welding: Complex joints such as ridges, gutters, and pipe penetrations are welded.
Surface Cleaning and Protection: Extreme care must be taken during installation to avoid scratching the surface.
