It is essential to consider physical factors like surface finish, uniformity and consistency within a wire when considering wedge wire for your application. Continuity of finish is an important factor for screens, particularly with architectural applications. In general, scratches and other visual defects will stand out in most screens quite easily. With architectural products the amount reflectivity can have a big impact and so can the consistency within the surface of the wedge wire. Visually, looking from panel to panel that can have an effect if one run doesn't look identical to the other.
When it comes to the wire itself, consistency within a spool of wedge wire is critical for making a successful screen. If the wedge wire manufacturer doesn't have the proper equipment or procedures in place for verifying uniformity within a spool the screen wire manufacturer runs several risks. Variations in the spool means variations within the slots of that screen. The best-case scenario is a potential rework of a screen, but then there's also the worst case scenario, where the entire screens ends up as scrap. Then all of the labor and time that went into the manufacturer of that screen is lost. Add to that a potential missed deadline to a customer.
