1.The angle
All of our products have a "3*90degree stardard"(1)The angle between top bar and low bar is 90 degree
(2)The angle at each corner is 90 degree
(3)The angle inside each corner is 90 degree
2.The top wire.It's nearly perfect straight after welding.For a 1800mm product,The STRAIGHT tolerance is< 0.5mm.(Not the size tolerance).It's very hard to achieve for a welding product.The advantage is whatever how long the project is,it looks like there is only one grate.Cause each line connects another exactly.
3.The welding point
Our welding point is very neat and clean.It needs a very high welding skill to make this happen.We do training for each workers hand by hand to ensure the quality
