Shaped tubes are made of all kinds of shaped seamless steel tubes by cold drawing. Special-shaped pipe is generally divided according to the broken section, according to the material can be divided into seamless steel tube, aluminum alloy special-shaped pipe, plastic special-shaped pipe.
Steel pipe special pipe can be divided into oval shaped steel tube, triangular shaped steel tube, hexagonal shaped steel tube, the diamond shaped steel tube, octagonal shaped steel tube, semicircle deformed steel circle, not equilateral hexagons five disc shaped steel tube, the plum flower form shaped steel tube, double convex shaped steel tube, double concave shaped steel tube, melon seeds shaped steel tube, the cone shaped steel tube, corrugated shape profiled steel pipe.
Special-shaped pipe, special-shaped square pipe, rectangular pipe, special-shaped welded pipe and spiral welded pipe, specification: 20*20mm-500mm, wall thickness: 0.6mm-20mm, spiral steel pipe. Specification of spiral steel tube, 219mm-2020mm, wall thickness 5mm-20mm. Straight seam specifications are 4 minutes, 6 minutes, 1 inch, 1.2 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, 4 inch, 5 inch, 6 inch, 8 inch, 102, 108, 127, 133, 139, 159, 168, 177, 194, 219, 273, 325 and other specifications of the special pipe generally refers to the rectangular steel pipe.
According to the section characteristics, the tubes can be divided into equal-wall tubes, hetero-wall tubes and variable-section tubes.
Isowall shaped tube Isowall shaped pipes are shaped pipes with the same wall thickness and different cross-sectional shapes. According to the shape of the section, it can be divided into two types: general isowall shaped pipes (FIG. 3-14) and isowall shaped pipes with folded bars (FIG. 3-15). Most of these shaped tubes are formed by cold drawing or continuous rolling of welded tubes.

Galvalume Steel Coil is a kind of Alloy-Coated Steel Sheet widely used in building materials, household appliances,automobiles, environment, machinery, ships and many other fields. The surface coating of galvalume steel sheet is composed of 55% aluminium, 43.5% zinc and a small amount of other elements. 1. Heat reflectivity: Aluminum-coated galvanized steel sheet has a high thermal reflectivity, which is twice as high as galvanized steel sheet. It is often used as insulation material. 2. Heat resistance: Aluminum-zinc alloy steel sheet has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. 3. Corrosion resistance: The corrosion resistance of aluminized and galvanized steel coils is mainly due to the protective function of aluminium and aluminium. When zinc is abraded, aluminium forms a dense layer of alumina,which prevents further corrosion of corrosion-resistant substances. 4. Economy: Because the density of 55% Al-Zn is smaller than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of galvanized steel sheet under the same weight and thickness of gold plating. 5. Easy to paint: Aluminum-coated galvanized sheet and paint have excellent adhesion and can be painted without pretreatment and weathering treatment. 6. Aluminum-galvanized steel sheet has a silver-white gorgeous surface.Read more
PPGL steel is an innovative product by combining the strength of steel with the anti-corrosive capabilities of coatings. It is short for pre-painted galvalume steel coil, which uses aluminum-galvanized sheet as base metal. The material is exceptionally resistant to corrosion and high temperature up to 315 degrees. PPGL coils are used in a wide variety of applications such as roofing & cladding, doors & windows, lighting, vehicle manufacturing, furniture, home appliance, and shipbuilding industry. Wanzhi Steel offers PPGL coil with width of 600-1,250 mm, and the thickness of 0.12-1.2 mm. There are also various colors and patterns to choose from. Welcome to contact us!Read more
