Jian-hung is a pipe factory to produce high-precision high-frequency welded steel tube-based manufacturer, factory was built in 2002, has many years of production experience, with professional technical production team, the introduction of a number of advanced high-frequency pipe production line, specializing in the production in the l age pipe, machinery and equipment, furniture, fans, shelves and many other industries, in industries with high efficiency in production capacity in a product with excellent cost-effective, in strict accordance with national standards of production, and strive to to achieve high quality and reasonable price, safety and environmental protection requirements! Factory product range: thickness 0.3mm-1.5mm cold-rolled steel hard materials, cold rolled black annealed steel pipe, cold rolled bright annealed steel and cold-rolled coil steel and can be tailor-made all kinds of square pipe, special-shaped tube, pipe and other steel and materials processing, to meet the full needs of all customers.

 

 

 

a) manufacturer capability: self-contained, master experience, monthly output is 1,000 tons or more.

 

 

Performance and advantages: good quality, high efficiency, cost-effective, can be bent, can be electroplating, spraying, electrophoresis, necking, punching, etc.

 

 

 

 

Product Usage: l age trolley, shopping, frame, iron curtain rods, iron pipe, fan tubes, furniture tubes, baby Che Kwun, etc.

 

 

 

 

 

b) Product Material:

 

 

1. Cold-rolled steel strip: It is hard material be divided into soft materials, hard materials without annealing hardness is relatively high, suitable for surface craft powder, ordinary electroplating and electrophoresis. Semi-rigid material is relatively soft after annealing, sub-one is three kinds of materials (coal back) Black back material, this material suitable for bending, contraction nozzle requirements of customers, can only be used to paint, powder, electrophoresis . One is the light back material (light material), flexibility is also relatively good, suitable for bending, contraction nozzle can be used to spray, powder, electroplating, electrophoresis, paint. One is the wide plate, flexibility is the best kind of strip, softness smoothness after the cold coil, suitable for bending, contraction nozzle, scrub, spray, paint, powder gel electrophoresis or a relatively high plating process customers.

 

2. Cold-rolled coil: It is white soft material, the relative softness of cold-rolled strip steel better and more excellent, more smooth surface, suitable for bending, stamping, shrink mouth, grinding, surface plating of higher customer demand relatively high, but also can be used to spray, powder, electrophoresis, paint.

 

           Indicate:

 

                               A. Because a variety of specifications, client requirements, not the same, use different materials, specific please call to discuss.

 

                               B. surface is mainly blank, but can be spray, powder, injection, can be plating.

 

                               C. the length of iron pipe is generally 4.5m-6.5m in length, but the customer require other sizes, to negotiate better conditions of production loss may be a corresponding cut factory issue.

 

                                D. price varies due to size, materials, prices vary, loss vary, the corresponding need for flexibility to mobilize factory.

 

                                E. Product size tolerance problems could exist.

 

                                F. iron pipe is welded, so there will be a black mark welding, surface technology for high welding marks the need for polishing.

 

                                G. square tube and some angles Rectangular pipe is not hard materials.

 

            H. oxidation because it is so rusty iron pipes is inevitable, but the system we will reduce to a minimum as far as possible, requesting understanding.
