I. Materials:
4 main materials are frequently used as gutter, they are steel plate, steel stainless, color-coated steel sheet and galvanized steel gutter
II. Scope application:
Generally steel plate gutter and steel stainless gutter are applied to steel constructions close to the sea or the places having strong corrosive gases around. While color-coated steel gutter is mostly used as exterior one.
III. Installation Instructions:
★ Steel Plate Gutter
1. Condition:
Finished column and beam fabrication, high-strength bolt twisted finally
2. Installation:
Make a full line along the gutter inside and outside and weld temporarily.
Make full weld at bottom side seam and sides straight seam with welding rod.
Make intermittent weld on connection between gutter bottom and top column.
Make down pipe holes along the steel column or steel beam side with torch cutting or angle grinder, then clean and painting.
★ Steel Stainless Gutter
1. Condition:
Finished column and beam fabrication, high-strength bolt twisted finally
2. Installation:
Argon-arc welding is adopted to steel stainless gutter, welding rod is stainless steel wire whose diameter is same as plate thickness, e.g. 1mm thickness.
Make spot welding to fix before welding, gutter bottom first, then the sides.
★ Color-coated Steel Sheet Gutter
1. Condition:
Finished roof sheet or roof panel fabrication
2. Installation:
Fix the inside of gutter and roof materials with self-tapping screw or rivet.
Make down pipe holes with cutting machine.
