Building Materials

Jinggong Science & Technology is a China construction materials machinery manufacturer. Our primary products include PU sandwich panel machine, high speed roll forming machine, steel deck forming machine, auto change purline machine, purlin forming machine, downspout forming machine, guardrail forming machine, as well as some auxiliary equipment such as slitter, uncoiler and stacker etc.

The following is a sample of some of our products:
Our PU sandwich panel machine mainly consists of uncoiler, film covering system, roll forming machine, preheating oven, electric control system, hydraulic system, and pneumatic system etc. It is highly efficient and easy to operate. Therefore, it is widely used in the construction of steel structure enclosures, cold storages and mobile buildings.

Our steel deck forming machine is extensively used in high steel structure buildings, which reduces floor load and eliminates the need for building formwork.

Our company is a professional manufacturer of cold roll forming machines in China. Based on the support from our holding company, we are specialized in providing high frequency welded pipe mill, sandwich panel line, steel coil slitting line, cut to length line, metal working, shot blasting machine, metal coil sheet, etc. Zhejiang Jinggong Science & Technology Co., Ltd supplies reliable and durable roll forming equipment or roll formers to our customers. We also have a professional service team, who can serve customers all over the world.

Jinggong Science & Technology has been a steel structure machine manufacturer since 1968. Throughout the 41 years of development, the company has expanded its production to include a wide range of products such as H beam welding machine, box column welding machine, gantry submerged arc welding machine, digital folder, slitting machine, and more. Here we give you some information about several types of our products.

Our H beam welding machine requires few operators and is suitable for large-scale welding jobs, bringing maximum value to users.

Slitting line and cut to length line are mainly used for pre-process of coil steel sheets. They are widely applied in industries like transformer, household electrical appliance, automobile, building material, packing, etc. Slitting machine is suitable for slitting kinds of wide steel strips into certain width, such as carbon steel coil, low alloy steel coil and stainless steel coil, etc. Then it recoils them to meet the requests of various procedures for welded pipes and cold rolled section steel production. Pipes produced by the slitting line are used in metallurgy, construction, transportation, machinery and vehicle industries. Cut to length line or cut to length machine is an automatic transversal cutting production line for cutting metal sheets.

Shot blasting machine adopts rotor blasting device to shoot the steel ball and blasts on the surface of steel workpieces so as to clear the dust, rust, burr or other objects on the workpiece surface. After shot blasting, the workpiece surface becomes clearer but more adhesive for painting. The interior physical character becomes more stable. Shot blasting equipment helps to prolong the life of workpieces. Zhejiang Jinggong Science & Technology Co., Ltd possesses engineers who own over 15 years of experience for shot blasting machines. This blasting machine is the first choice in domestic market.

We have a professional technical team of first-class rich experience and well-trained technicians. The metal coil sheet and metal corrugated panel products developed and designed by us meet the international standard. Our steel coil products have been used and widely praised by clients from more than 30 countries and areas, such as Russian, Brazil, India, South Africa, Germany, USA, Mexico, Saudi Arabia, and so on.
