BBN's Machining Platform is a comprehensive machining service platform with well-equipped machine, which are imported from Japan, German, Italy, South Korea ,Taiwan and so on. Our company has large, medium and small gantry five-face maching center, Floor-Type Milling-Boring Machine, Portal-Type Processing Center, Vertical Lathe, Deep-Hole Drilling Machine, Multi-Drilling Machine and Planer, etc which are multistandard, high-precision and multi-function. What's more, there are a large number of technical professionals in our company, and through many years' foreign processing services, they have accumulated rich experience in stainless steel, carbon steel, special steel, forging and casting, etc.

BBN's Heavy Industry welding platform is in possession of the welding capacity of the large scale steel structure, duplex steel ship plate, vessel shell and precision sheet metal. The welding methods include submerged arc automatic welding, narrow gap welding, argon arc welding, shielded metal arc welding and plasma welding and so on. The weldable materials include carbon steel, alloy steel, stainless steel and the non-ferrous metal such as copper, aluminum and titanium. There are more than 200 sets of various welding equipments, among which the SAF plasma welding machine can weld 12.5 meters seam of flat butt welds at one time, refreshing the world record for the length of this model. In the meantime, company also has H-profile Steel Production Line, large-scale Edge Planer, Heavy-Duty Rolling Machine, NDT Room with length over 30 meters, Heat Treatment Furnace, Blasting Room and other Large-Scale Equipments. Currently, there are also several engineers with CSS, LR and special equipment Welding Certificate.
