Galvanized (GI) Square Tubes
Galvanized (GI) Square Tube Distributor in the Philippines
Galvanized or GI square tube is made of a type of steel that has gone through the galvanization process. This procedure involves immersing the pipe in a molten zinc bath to provide it with a touch, uniform barrier, or coating. The method also gives the galvanized (GI) square pipe improved corrosion resistance compared to other tubes made of carbon steel.
In addition to its exceptional corrosion resistance, a galvanized (GI) steel tube offers several other advantages. Its zinc coating provides added protection against scratches, abrasion, and impacts, making it highly durable and resistant to wear and tear.
Moreover, galvanized (GI) square steel tube is known for its high strength-to-weight ratio, making it a lightweight yet robust option for various structural applications. Its ease of fabrication, wide availability, and cost-effectiveness further contribute to its usefulness in construction, manufacturing, and other industries.
