Metal sheet metal structure of the manufacturing presentation

Manufacture of metal structures refers to the production activities of metal components, metal component parts, construction steel products and the like, mainly made of metal such as iron, steel or aluminum. These products can be shipped and easily assembled, installed or erected (as built by a construction firm at a construction site).


- Metal structures for construction, components: metal roofs, metal roof frames, metal columns, etc .;

- metal bridge structure and bridge parts, iron tower, iron frame, metal pillar, metal girder, mine mouth metal framework, sluice and wharf and other metal components;

- Metal mobile homes;

- steel scaffolding, metal pillars for metal formwork or tunnel support, and the like;

- Processed metal sheets, metal rods, metal profiles, metal profiles, metal pipes and the like and their component parts for the above structures.


The main purpose of Dalian sheet metal parts

Suitable for stamping process sheet metal material is very large, widely used in electrical and electronic industry sheet metal materials include:

⒈ ordinary cold-rolled plate SPCC SPCC refers to the continuous rolling of the ingot through the cold rolling mill into the required thickness of the coil material or sheet. SPCC surface without any protection, exposed to the air can easily be oxidized, especially in humid environment, accelerated oxidation, the emergence of dark red rust, when used to paint the surface, electroplating or other protection.

⒉ galvanized steel SECC SECC substrate for the general cold-rolled coil in the continuous galvanized line after degreasing, pickling, electroplating and a variety of post-processing process, which became electrogalvanized products. SECC not only has the general cold-rolled steel mechanical properties and approximate processibility, but also has excellent corrosion resistance and decorative appearance. In the electronics, home appliances and furniture market has great competition and substitutability. For example, the computer chassis is commonly used SECC.

⒊ Hot dip galvanized steel plate SGCC hot dip galvanized steel coil refers to the hot-rolled pickling or cold-rolled semi-finished products, after cleaning, annealing, immersed in a molten zinc bath temperature of about 460 ° C, and the steel plate Zinc layer, then quenched and leveled and chemical treatment made. The SGCC material is harder than the SECC material with poor ductility (avoiding deep draw design), a thicker zinc coating and poor weldability.

⒋ stainless steel SUS301 Cr (chromium) content lower than SUS304, poor corrosion resistance, but after cold work can get good tensile strength and hardness, good elasticity, and more for the leaf spring and anti-EMI.

⒌ Stainless Steel SUS304 One of the most widely used stainless steels, Ni-containing steel is more corrosion-resistant and heat-resistant than Cr-containing steels. It has very good mechanical properties, no heat treatment and hardening, no elasticity .
