We are a reference point for the market of wholesale for hot dip galvanized screws and bolts. Hot Dip Galvanizing is a process developed to prevent steel from corroding. Low initial cost and long life make galvanizing the most versatile and economic way of protecting steel for long periods. This protection system is mechanically very resistant, allows to obtain a significant thickness and, therefore, a high corrosion resistance.
