Coating Lifespan & Thickness Calculator
Estimates your zinc coating spec and maintenance-free service life for your steel thickness and environment.
Zinc loss rates by environment: C2 ≈ 0.7 µm/yr → CX ≈ 8.0 µm/yr.
Indicative estimate — actual life depends on exposure, edge condition and steel surface prep.

The 6-Stage Galvanizing Lifecycle
Select a stage to see what happens to your steel at each step.
1. Degreasing & Alkali Rinse
Steel is cleaned in a hot alkaline bath to remove oils, grease and shop dirt. A clean surface is essential — any contamination here shows up as bare patches in the finished zinc coating. Parts are then rinsed to remove residual alkali before pickling.

Quality Assurance, Batch by Batch
Every batch is processed and quality-checked against our in-house control plan — no shortcuts, no exceptions.
Zinc coating thickness tuned to steel section thickness — thick enough to protect for decades, even in coastal salt air.
Every batch is checked with magnetic coating-thickness gauges, plus visual and adhesion inspection before dispatch.
Coating thickness and bath records are kept for every batch and issued with your dispatch — traceable quality, in writing.
Fabrication and galvanizing in-house means no bare welds, no third-party handling damage, no gaps in the coating.

09 — FAQ
Galvanizing Questions — Answered
Straight answers on pricing, turnaround, standards and what you can send us.
What is hot-dip galvanizing?
Hot-dip galvanizing immerses prepared steel in a molten zinc bath at ~450°C, creating a metallurgically bonded zinc coating (typically 40–120 µm) that protects against corrosion for decades. It is the world's most widely used corrosion protection for structural steel.
How much does hot-dip galvanizing cost in Pakistan?
Galvanizing is priced per kg and varies by section size, surface condition and order quantity. Our current rate ranges from PKR 180–300 per kg; for quantities above 20 tons, the minimum rate is PKR 180 per kg. Thin sections carry more surface area per kg, so they sit at the upper end of the range. Send your item list and tonnage for an exact same-day quote.
What is the maximum steel length you can galvanize?
Our kettle accepts sections up to 27 ft (8.2 m) in a single dip — no splices. Longer assemblies can be designed in two pieces and bolted after dipping.
How long does galvanizing take?
Standard galvanizing jobs are completed in 24–48 hours after receipt. Fabrication plus galvanizing turnkey packages typically run 1–3 weeks depending on complexity.
Do you fabricate steel before galvanizing?
Yes. CAD detailing, CNC plasma cutting, certified MIG/TIG/arc welding, trial assembly and then hot-dip galvanizing — the full cycle is done in-house under one roof.
Do you issue test records with every batch?
Yes. Every batch is checked with magnetic gauges for coating thickness, plus visual and adhesion inspection. Coating thickness and bath records are issued with every dispatch.
Can you re-galvanize existing or rusty steel?
Yes. We sandblast existing steel to near-white metal, re-galvanize it, and touch up damaged coatings. We also service and repair galvanized structures in the field.
Do you deliver across Pakistan?
Yes. We arrange transport across Pakistan — including Lahore, Islamabad, Hyderabad, Sukkur and all major industrial zones.
