Cold formed rectangular hollow section (RHS) is formed from hot rolled coil and has a smooth blue/grey coloured finish and a raised internal weld seam that can vary greatly depending on the mill of manufacture. Coils vary in size up to around 25 tonnes and 2 metres wide. Cold Rolled Steel Rectangular Tube Metal Supermarkets Cold Rolled Steel Rectangular Tube is cold rolled steel that has been formed into a rectangular tube. It is commonly referred to as HSS, meaning Hollow Structural Section. It is measured by taking the outer walls (which are different dimensions) and then the wall thickness. Used in general fabrication where strength is a requirement.
Cold Rolled Steel Uses There are many uses for cold rolled steel products, such as sections and tube, angle sections, T-sections, open box sections, sheets and strips. These are used in garage doors, conveyors, security grills, storage racking, live storage, cladding and industrial partitioning.

Sep 11, 2014 · Customers often ask us about the differences between hot rolled steel and cold rolled steel.There are some fundamental differences between these two types of metal.The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. HOLLOW STRUCTURAL SECTIONSand processed through a set of sizing/shaping rolls which cold-form it into a round (9), square (10) or rectangular (11) section. Form-Square Weld-Square (ERW) Process In the weld mill, driven forming dies progressively shape the at strip (1) by forming the top two corners (2) of the square or rectangular tube in the initial forming station.

Weight Calculator. Metal gets heavy, and whether you want to see how much shipping is likely to be, or if your vehicle (or back) can handle it, its good to know what your order weighs. To help with that, weve got our handy weight calculator here. Fill out the information below and it will tell you how heavy that piece of material is. RECTANGULAR HOLLOW SECTIONS - Steel Tube ManufacturerRectangular Steel Tubes. Rectangular hollow sections or rec tubes are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. In order to form the rectangular steel section the appropriate mother tube, a round steel tube, has to be formed first.
