spray the bare steel in the weld zone with a zinc rich paint. The fumes that are generated have been measured by Orrcon Steel to be below TWA and STEL limits. Weld fumes are low due to the water based Clear-Tec coating and the controlled and uniform thickness. BlueScope steel coil to AS1397 confers guaranteed zinc-coating performance and steel DuraGal Easy Welding Guide - AusTube MillsThis guide applies to welding techniques for low carbon steel (CE0.39) used in the DuraGal® hollow sections and profiles. These sections, with their lustrous, thin, evenly applied zinc and zinc aluminium coatings are as readily welded as black steel. Using this guide will assist in achieving the best possible appearance and the
HOLLOW SECTIONS IN STRUCTURAL APPLICAT IONS by J. Wardenier PREFACE Professor Jaap Wardenier has had an enormous impact on the design methods for tubular steel structures in the late 20th. century. The Rectangular Hollow Section is veritably his progeny and it has grown up to be a respectable member of the steel society under his tutelage. HSS Splices Steel Tube InstituteThe familiar steel construction maxim of weld in the shop, bolt in the field, naturally applies. Bolted Splices. Bolts Loaded in Shear. Due to the closed shape of the cross section, bolting directly into the walls of a hollow section is difficult with regular high-strength bolts. Hollow Sections Rectangular Square Mild steel for Rectangular Hollow section & Square hollow Section features a high strength to weight ratio that results in savings in steel and costs. The sections are best suited for welding, are corrosion resistant, and easily bendable which leads to the shaping and construction of aesthetically appealing structures without compromising on strength and durability.

The EN specifications stated above replaced the following DIN (German institute for standardisation Structural hollow sections - SSAB - SSABWith SSAB's structural hollow sections, you can significantly reduce the weight of your steel structures while gaining savings in material and manufacturing costs without limiting the freedom of design. You can also choose from several shapes of hollow tube, including square hollow sections and rectangular hollow sections.
These include steel sections such as D-sections, Flat or Elliptical Oval Tubes, Triangle Profiles and Dome Profiles to name some of the more standard steel welded profiles. We are most certainly not limited to only these sections but do have some advice on how to keep your tooling cost (needed to manufacture the steel closed profile) to a minimum. telescoping RHS - AusTube Millsd b ttop side d b mm mm mm mm mm mmmm Square Hollow SeCtioNS 13 13 1.8 No Section 15 15 1.8 Available 20 20 1.6 1.8 1.8 15 15 The internal weld bead and variation in corner Select the appropriate table for the type of hollow section required.
