building material square and rectangular tubes

square and rectangular tube 2.Galvanized,painted,oiled are available 3.delivery quikly 4.different sizes

Square/Rectangular tube is applicable to frame for civil construction, furniture and etc.. We can supply the products according to following standards:

GB/T6728-2002   ASTM A500 Gr. A.B.C.   JIS G3466

Different appearance of the surface:

1.BRIGHTEN:

Brighten steel pipe is made of brighten annealed steel strip (a kind of material corresponding to CR). Similar with black tube made of cold rolled coil, brighten steel pipe keeps the original brighten color of steel.

2.PRE-GALVANIZED:

Pre-galvanized tube is made of hot dipped galvanized steel strip directly.

3.HOT DIPPED GALVANIZED :

Hot dipped galvanized tube owns thicker zinc coating than pre-galvanized tube. Black tubes will be dipped into zinc pool for galvanizing.

4.ELECTRO-GALVANIZED:

The technology of electro-galvanized tube is similar to hot dipped galvanized tube, but the thickness of zinc coating is less than hot dipped galvanized tube.

The dissimilarity of workmanship among hot dipped galvanized tube, per-galvanized tube and electro-galvanized tube results in different level of erosion resistance and cost.

The performance of hot dipped galvanized tube is the best, then pre-galvanized tube, and last electro-galvanized tube.

Company Profile:

TIANJIN WEIMING (WMITC) STARTS WITH

NON-STANDARD, CUSTOMIZED STEEL PROCESSING

 

        In year 2010, WMITC sets up a new factory in Baodi Jiuyuan Industrial Park—Green (Tianjin) Technology Development Co. Ltd. (GreenTech). GreenTech is the only manufacturing company in Tianjin who specializes in the R & D, production and installation of wind, sand, snow and dust control systems with the steel porous panel they produce. GreenTech has established close cooperation relationship with several authoritative universities, research and design institutes, and has passed the authorization and the audit of ISO9001:2008, ISO14001:2004, ISO18001:2001. Since the factory came into output in July, 2011, GreenTech has completed nearly 20 projects in China and South-east Asia.

Green (Tianjin) Technology Development Co. Ltd.—Wholly owned by WMITC

 Steel porous panel produced by GreenTech

Windbreak and dust suppression wall built by GreenTech in Jingtang Port, Hebei Province (the net on the steel structure is steel porous panel).

Sand Barrier built by GreenTech alongside Lhasa-Shigatse railway in Tibet (the net of grey and green are steel porous panels)

Heavy wind barrier on the railway bridge through windy area of north west China

To satisfy the R& D and production request, GreenTech owns advanced equipments and test machines especially for steel.

  

        Taking the advantage of GeenTech’s equipments, WMITC is able to do non-standard, customized steel processing according to the drawing or sample supplied by the end users. The following is a brief introduction of processing capability for part equipments and production lines.

Steel Processing List Non-standard, customized steel processing according to drawings and samples   1.  Cut steel coil into steel sheets Raw material: Cold rolled coil, Galvanized steel coil, Prepainted steel coil Input raw material size: thickness 0.3-2.0mm                                    width 500-1600mm Output steel sheet size: 500mm x 500mm (min.)                                    5000mm x 1500mm (max.)   2.  Slit steel coil and recoil Raw material: Cold rolled coil, Galvanized steel coil, Prepainted steel coil Input raw material size: thickness 0.3-2.0mm                                     width 500-1600mm Output steel coil size: 10mm (min.) x coil   3.  Steel strip cutting, slitting, recoiling Raw material: Hot rolled steel strip, Cold rolled steel strip Input raw material size: thickness 0.8-6.5mm                                   Width 100-600mm Output material: steel plate, recoiled steel strip   4. Cut to length flat bar Cut to length flat bar is made from hot rolled steel strip which is uncoiled, slit, leveled and cut to certain length and width. Comparing with hot rolled flat bar, cut to length flat bar has a better accuracy in size and a better flatness. Size: thickness 9mm (min. ) length as ordered   5. 315M/T – 45M/T punching processing Our company owns punching machines ranging from 315M/T to 45M/T. With advanced equipments, we are able to supply high quality metal process by punching machines and other affiliated equipments. Metal materials can be processed: aluminum, copper, stainless steel, aluminum alloy, steel Sizes of processed metal: plate 1250mm x 2500mm (max.) Surface treatment: electrostatic powder sprayed or according to requirement   6. CNC flame cutting   7. Welded T bar   8. Electrostatic powder sprayed coating Advanced technology equipment which is specially designed for long and heavy steel. Processing range: pipe, beam( C\Z\Y\U\H\T) and other metal materials with cutting surface of 400 x 1500mm within 6m in length.   9. Steel plate bending   10. Pipe and beam cutting and bending   11. Other metal parts processing combining multi-processing technology
