DX51D is a European standard. 

A53 seamless steel pipe is an American standard steel pipe that is divided into two types: A53A and A53B.Among them, A53-A is equivalent to China’s 10# steel, A53-B is equivalent to China’s 20# steel, and A53-F is equivalent to China’s q235 material. 

Galvanized grating is a rust-proof treatment carried out after the steel grating is produced. 

Hot rolled carbon steel is an alloy formed by mixing iron and carbon, with a carbon content of between 0.06 and 2.11 percent.

A53 galvanized steel pipe is a steel pipe product commonly used in industry and construction. 

I-beam is a common structural steel with light weight, high strength and easy construction. 

Galvanized steel coil Z275 is a type of steel sheet that has been coated with a layer of zinc on its surface.

Galvalume steel coil has a characteristic smooth, flat and ornate starburst surface with a silver-white base colour. The special coating structure gives it excellent corrosion resistance.

MS stands for “mild steel,” referring to the material’s lower carbon content. One of the hot rolled steel sheets is mild steel plate with plate number SS400.

Hot rolled steel plate is a very common metal material, which is widely used in construction, ships, bridges, automobiles, pipelines, machinery manufacturing and other fields due to its excellent physical and mechanical properties.

Deformed reinforcing steel bar is one kind of reinforcing steel bar. 

Colour coated aluminium sheet is a building material with a wide range of uses, mainly used in indoor and outdoor decoration, billboard production, body cargo box, electronic and electrical shells and other fields.

Colour coated galvalume sheet is a kind of building material made of three-layer composite material of substrate, zinc-aluminum alloy coating and organic coating, which is usually made of the substrate after surface treatment, coated with zinc and aluminum alloy layer, and finally coated with organic coating.

Flat bar A36 is a common building material, often used in support structures, bridges, construction and machinery manufacturing.A36 is an American Standard carbon structural plate, which conforms to ASTM A36/A36M-03a.

Any series of industrial aluminum alloy coils are rich in chemical elements. For example, zinc, chromium, silicon, iron, manganese, magnesium, titanium, copper and other metal elements, adding different proportions of different metal elements, then the performance of aluminum alloy will also change.

Flat bar steel is steel with a long cross-section, and commonly used materials include ordinary carbon steel, alloy steel and stainless steel. The shape of its cross-section is characterized by flatness. Flat steel is characterized by uniform material, easy delivery, and moderate price, and widely used in various fields. 

Galvanized flat steel in fact refers to a 12-300 mm wide, 3-60 mm thick section of rectangular and slightly with tons of edges of a steel, which can be used as a finished steel, but also as a galvanized pipe billet and galvanized strips, as a finished product can be used in the production of hoops, tools and machinery parts, if used in construction can be used as a structural member of the frame and escalators.

Hot rolled galvanized steel is a hot plate as a substrate after pickling directly galvanized, compared with the traditional galvanized sheet, due to less cold rolling this process and has a clear price advantage, in the construction, automobile manufacturing, steel plate warehouse manufacturing, railroad bus manufacturing, highway guardrail plate, manufacturing and other industries have a good prospect for development.

SPCC-SD denotes standard tempered, non-gloss finish rolled, cold rolled carbon steel plate and strip for general use, single gloss linen material, with a Vickers hardness (HV) between 85 and 110.

5000 series aluminum alloys have excellent properties such as good strength, ductility and weldability, and are widely used in aviation, aerospace, automobile manufacturing and other industries.
