At Urbanfab, hot‑dip galvanizing is a core part of our engineering philosophy. Every mild‑steel product we manufacture is hot‑dip galvanized after fabrication to ISO 1461:2022, creating a zinc–iron alloy armour that grows into the steel and protects from within, ensuring long‑term durability, dependable corrosion protection and performance you can trust.

• Built to Resist Corrosion

Hot‑dip galvanizing protects steel with a tough, metallurgically bonded zinc coating that delivers long‑term corrosion resistance. The zinc layer also provides sacrificial (cathodic) protection, meaning it continues to safeguard exposed areas of steel if the coating is scratched or damaged.

• Protection Where You Can’t See It

Hot‑dip galvanizing is far more than a surface finish. The completed steel fabrication is fully immersed in molten zinc, forming a bonded zinc–iron alloy layer. Our mild steel is engineered to allow molten zinc to reach welds, joints and internal cavities — protecting the internal areas you can’t see and delivering decades of corrosion resistance. This ensures the structure is protected at its core, not just on the outside.

• Made for the Long Term

Hot-dip galvanized mild steel is renowned for its long service life. The zinc coating provides durable, predictable corrosion protection, helping products remain functional and structurally sound for many years with minimal intervention. Fewer repairs. Fewer replacements. Greater confidence in the long‑term performance of your investment.

• Low Maintenance. Lasting Protection.

Once hot-dip galvanized, mild steel requires significantly less maintenance than many conventional coating systems. The zinc coating protects the underlying steel throughout its service life, reducing the need for regular repainting or surface treatments. This lowers lifetime maintenance costs and ensures consistent, reliable performance.

• Built for Tough Conditions

Outdoor steel structures face constant environmental challenges — moisture, temperature shifts and pollution. Hot-dip galvanizing delivers a robust protective system built for these demanding environments. It’s ideal for shelters, bin stores and other outdoor steel products that must endure year‑round exposure. 

• 150+ Years of Proven Protection

Hot‑dip galvanizing has been used for more than 150 years to protect fabricated steel. Its long history, established standards and proven performance make it one of the most widely recognised and trusted corrosion‑protection methods across industries such as construction, infrastructure and agriculture, where long‑term corrosion resistance is essential to safety and structural integrity.

• Our Standard: Hot‑Dip Galvanized to ISO 1461:2022

At Urbanfab, we don’t simply describe our products as ‘galvanised’. We galvanize to ISO 1461:2022, the recognised international standard for protective zinc coatings on fabricated steel. This standard defines how the steel is prepared, coated and inspected — ensuring a consistent, high‑quality protective finish on every product we manufacture.

• Built to Last. Protected to the Core.

For us, hot-dip galvanizing is part of how we build. From cycle shelters and bin stores to smoking shelters and outdoor steel structures, we choose hot‑dip galvanizing because it delivers durable corrosion protection, low maintenance and long‑term value.
