Product Description

Spiral Steel Pipe rust mainly using tools such as steel wire brush the surface grinding, cleaning and pre-heating coil can be removed loose or tilt of the oxide scale, rust, welding slag. Hand tools rust can reach Sa2 level, power tools rust can be achieved Sa3 level, if the coil attached to a solid surface oxide skin, tools rust effect is not ideal, of the anchor pattern depth of less than anti-corrosion construction requirements.
