20×40 Galvanized Rectangular Steel Tube Requests | Pre-Galvanized or Hot Dip GI Hollow Section
Galvanized hollow steel tube has actual lengths of 6m, 6.4m and 12m with 0.5–6.5mm or customized wall. The body lists square, rectangular, round or customized shapes and a 1–12m length range.
The title requests a 20×40 rectangular section, while body size examples are square. Provide the outside dimensions and wall together. Pre-galvanized and hot-dip wording need a selected coating route and acceptance basis; the source gives zinc coating without its numeric requirement.
Select one substrate grade from the broad catalogue and define cut length and joint requirements. The general ASTM reference does not establish every grade or manufacturing route. Building and fluid-pipe application labels provide no verified structural capacity or pressure qualification for the selected hollow section.
