9 Our company information:
Tianjin Emerson Commercial and Trade Co.,Ltd located in Tianjin, China, providing construction materials: steel plate, steel sheet, steel coil, steel pipe, steel rod, steel beam, steel channel, angle bar, and hollow sections. Except these products, we also supply steel structure construction, scaffolding, steel formwork, machinery, and fabrication service, and provide purchasing service for foreign companies purchasing in China. We hold large stock for steel coils and steel sheets, so can do immediate shipment for stock available sizes, for new production, we make very short production time to make fast delivery, even special dimensions. We do OEM. We cut steel coils into steel sheet cutting to length line, or cut steel coils into steel strips with small width for clients. We cut steel plate by flame cutting, laser cutting, water jet cutting to all shapes as clients’ drawings; we welding, bending, make plates into steel structure, machine parts and make machines. We bend steel pipes, cut and weld the pipes into steel structure parts, make all by clients’ drawings. We do Quenched and Tempered heat treatment for steel rod and round bar to maintain its hardness, then do turning and do thread by machining, and do UT on the finished machined rods. We can help foreign companies to purchase, we can handle all types of products purchasing in China. Service wins the future, we do prime quality, fast delivery, and good service, welcome everyone cooperate with us. Waiting you!
