Stainless steel wedge wire screen/Johnson type screen provides the maximum inlet area of any well screen design. This screen is versatile and can be adapted to many industrial functions. The strength and durability of this type of screen comes from the shape and mass of the wrap wire and rods combined with the efficiency of the welding techniques used in manufacturing.

The special trapezoidal shaped wire is drawn from carefully specified material, double-annealed and roll formed to precise desired dimensions. The wire is then spiral wrapped around the longitudinal rods of the same material and resistance welded at each point of contact.
