Galvanized Wires

As a leading Galvanized Wires Manufacturer in Kolkata, Group Nirmal offers GI (Galvanized) wires ranging from 1.5mm to 6mm, with zinc coating levels between 40gsm to 500gsm. All products adhere to IS, BS, DIN, ASTM, and JIS quality standards.

Galvanized wires are the ultimate solution for protection against rusting and corrosion, thereby securing assets. Galvanised steel wire is a versatile product that undergoes galvanization—a chemical process where zinc is applied to provide a rust-preventing layer. This makes GI wires strong, rust-resistant, and suitable for various applications.

Galvanized steel wires are widely used as binding material in construction due to their high strength and durability. Moreover, GI wires are weatherproof and enhance the value of properties and buildings, which is why Group Nirmal is a top choice as a Galvanized Wires Manufacturer in Kolkata.

Galvanized Wire Fences

Traditional fencing materials like wood, stone, or plain wire can rot, crack, or rust over time. The solution lies in Galvanized Wire Fences. Normal steel wires tend to rust even with slight rainfall, as oxygen in the air produces iron oxide—rain being a catalyst. However, with galvanized steel wires, the zinc layer used in the galvanization process significantly slows down this chemical reaction.

At Group Nirmal, a seasoned Galvanized Wires Manufacturer in Kolkata, we bring over 20 years of experience in deploying green manufacturing processes for GI wire fences. Our fences meet Indian Standard (IS 278) and are applicable in both defence and civilian infrastructure. For barbed wires, we offer a unique, safe packaging solution that ensures user-friendly handling and client safety.
