Reason for selection:
Synthetic resin is a common material for basic packing of wooden houses.
Packing made of stainless steel, which has higher strength than the resin,
has been recently developed. 21%Cr, a ferritic stainless steel type, has
been adopted for its superb cost performance.Higher strength of stainless
steel compared with synthetic resin, has made it possible to narrow the
width of vent holes by 9mm, resulting in better quake resistance and elimination
of rat trap devices. Other advantages of stainless steel include higher
fire resistance and longer product life.The use of this type of packing
is steadily on the rise, contributing to increases in stainless steel demand.
