Transmission Line Steel Tubular Pole We
have got 220kV Transmission Line poles Quality Certificate from Power
Industry Steel Tower Qualified Inspection & Test Center from 2001
year. Our steel poles are made from quality sheet through bending,
forming, automatic welding and hot galvanization. We can reach one-run
machining length of 14m and can bend sheet of thickness up to 45mm. We
adopt advanced welding procedures, automatically weld main joints and
reach rank-II welding quality.
We have supplied 2400ton 132kV and 220kV transmission line steel pole to
WAPDA. Pakistan on 2008 and have supplied 1200ton 138kV transmission
line steel pole to Davao light, Philippines on 2009.

Most of the brake pads we had developed in our factory are for passenger cars brake pad, auto brand including all kinds of vehicles for: Toyota, Honda, Isuzu, Nissan, Mazda, Daewoo, Hyundai, KIA.
The main specification we adopted for our production and inspection showed as follows:
GB /T5763-2008 Automotive disc brake pad inspection standard
GB /T17469-1998 Inspection specification for Automotive brake pads friction property
GB/T5766-2006 Friction material Rockwell hardness
According to the above national specification, we have formed our own work flow:
Powder weighing- powder mixing-cold pressing- back plate degrease-back plate blasting- hot pressing for friction powder and back plate- heat treatment for the rough unfinished brake pads surface grinding-cutting grooves- chamfering- cleaning-painting- accessories installation- printing- finished products -inspection-packing.
For each batch of production, we will test a certain numbers of finished products by instant, and test the friction of coefficient/wearing rate property to make sure it is with the required specification.
Our Brake pads friction coefficient is between: 0.34-0.50 (10-7 cm3/ N. M), which is within the national specification, and hardness is 90 HRR or so;
For bake pads production and inspection, we strictly follow the national technical specification for brake pads GB 5763-2008, based on this standard, we have formed our own production procedure, the simple brake pads work flow in our factory showed as follows:
Step 1: Powder weighing- powder mixing-cold pressing for friction powder-
Step 2: Back plate degrease-back plate blasting-
Step 3: The hot pressing for friction powder and back plate- heat treatment for the rough unfinished brake pads surface grinding-cutting grooves- chamfering- cleaning-painting-
Step 4: Accessories installation- printing- finished products -inspection-packing
For our customer's selection about our material formula, there are several main brake pads formulas in our factory include the semi-metallic, and the NAO(non-asbestos organic). We no longer produce the asbestos material. But with the different percentage of the steel fiber and other stuffs, we have divided our semi-metal and NAO formula as follows:
A. Regular NAO formula;
B. Steel fiber formula;
C. Steel fiber with non-asbestos formula;
D. Non-asbestos with compounded fiber formula;
E. Semi-metallic formula
We suggest our customer make the selection according to the local market requirement to decide the specific materials.
