Mild steel sliding door bolts are simple locking fittings used to secure doors, gates, and shutters with the help of a padlock. They are made from mild steel, which provides good strength and makes them suitable for regular use in homes, shops, and industrial areas. The bolt works by sliding a metal rod into a fixed bracket, helping keep the door properly closed.
To make sure these bolts meet proper quality and safety requirements, BIS certification
under IS 281:2009 is required. This standard sets guidelines for material, size, design,
and performance, ensuring the product is checked before being sold in the Indian
market.
