Cold Formed Purlins C & Z - EEC Group

EEC purlins are made of black or galvanized steel strips, cold formed into C & Z profiles of different sizes. Their thickness can be up to 3 mm and the length is according to client specification. Because of their light weight, high quality, durability and lower total cost, these purlins are the best alternative to the equivalent standard steel sections.

Jul 02, 2020 · Cold formed Hollow Structural Sections (HSS) are commonly hot-dip galvanized for a variety of projects and industries because full immersion in the galvanizing kettle allows full coverage including interior protection from corrosion. Design of Products to be Hot-Dip Galvanized After Most iron-containing (ferrous) materials are suitable for hot-dip galvanizing. Plain carbon steel (under 170 ksi or 1,200 MPa) and low alloy materials, hot-rolled steel, cold-rolled steel, cast steel, ductile iron, cast iron, castings, stainless steel, and even weathering steel can be and are galvanized for enhanced corrosion protection. GB/ T 6728-2002 Cold formed steel hollow sections for Apr 29, 2020 · GB/ T 6728-2002 Cold formed steel hollow sections for general structure . Th e s tandard is applicable to round, rectangular and square cold forming hollow sectional steel made of cold-rolled or hot-rolled steel plates, sheets and strips on continuous roll cold forming units. It is also applicable to continuous hot-dip plated sectional steel. However, it is not applicable to sectional steel

Hot dip galvanized, pre-galvanized and electro-galvanized

The hot dip galvanizing process is where an already formed part, for example plate, round, square or rectangular tube is dipped in a zinc bath. A reaction takes place between the steel and the zinc during the time the part is in the zinc bath. Hot-dip galvanizing of cold-formed steel hollow sections Download Citation Hot-dip galvanizing of cold-formed steel hollow sections:a state-of-the-art review A good understanding of the effects of galvanizing on the short- and long-term behaviours Structural Steel Sections Price, 2021 Structural Steel Structural Steel Sections Price - Select 2021 high quality Structural Steel Sections Price products in best price from certified Chinese Structural Steel Bar manufacturers, Building Structural Steel Plate suppliers, wholesalers and factory on Made-in-China

Hot-dip galvanizing is one of the oldest and most common types and has been used to fight corrosion for more than 200 years. Hot-dip galvanizing is a process in which a steel article is cleaned in acid (pickled) and then immersed in molten zinc that is heated to approximately 850° Fahrenheit. Sturdy, Stainless cold formed hollow steel for Industry The cold formed hollow steel you can find on the site are generally built using hot-dipped technology to prevent rusting and weakening of the structural elements. With seamless welding quality, these cold formed hollow steel are annealed with nitrogen protection and are polished with utter professionalism.Hot-dip galvanizing of cold-formed steel hollow sections techniques, hot-dip galvanizing is a cost-effective measure for corrosion protection. Galvanized steel structures are often maintenance-free since the service life of the zinc coating generally exceeds the design life of the structure it protects [2]. In addition, the shiny appearances of galvanized steel structures, such as the iconic VIA 57
