Some level of variation should be expected when ordering No. The variations arise from differing manufacturing conditions, such as wearing of the abrasive belts used in these finishes. 4 Brushed finish can vary with different suppliers and even from batch to batch from the same supplier.
Three more common stainless steel finishing options are: Consequently a new surface finish description was introduced which remains in use to this day. However, it was soon discovered that some of these dull polished finishes had poor corrosion resistance, especially when exposed to seawater. Further testing revealed that steel with high surface roughness was heavily damaged by the polishing operations, whereas steel with low surface roughness was relatively unscathed.ĭuring the mid-1980’s dull polished finishes became widely used on projects such as high-profile architectural projects. The development of the surface finish standardĭuring the late 1970’s, British Steel scientists found that dull polished finishes on stainless steel showed a wide range of surface roughness. The choice of finish should always be clearly specified and properly defined by standard industry designations. Smooth surface finishes are better where the steel will be blended. Rough surface finishes are appropriate when the steel will be ground prior to painting and gluing. The choice of surface finish is also important where fabrication processes will be applied. 4 finish is one of the most popular finishes available. In retail products, particularly kitchen appliances, stainless steel No. For example, in architecture and the automotive industries, different finishes can be used to achieve a variety of visual effects. In projects when design is a primary consideration, an attractive finish will enhance the appeal of the end-product. Whatever the intended use, choosing the right finish option is essential. There are a number of stainless steel finishing options that alter more than just the appearance of the material.
