What this ZRC Cold Galvanizing Compound (ROVAL) does
ROVAL ZRC Cold Galvanizing Compound is a single-pack, ready-to-use, zinc-rich cold galvanizing compound used to protect steel and ferrous metals through galvanic anti-corrosion performance. It is designed for high-risk rust-start points such as cut edges, weld seams, drilled holes, fasteners, damaged galvanized areas, and maintenance repair zones where conventional barrier-type anti-corrosion paints may fail earlier after scratches or edge damage. It is used for fabrication, restoration, and maintenance work on steelwork in industrial and outdoor service conditions, including projects across Lahore and Pakistan, especially where an on-site, galvanizing and cathodic protection approach is required.

About the Product
The Pakistan corrosion problem it addresses
Steel in Pakistan often starts corroding at weak points such as weld seams, cut edges, drilled holes, bolts, and outdoor joints. In many fabrication and maintenance jobs, moisture, dust, industrial pollution, and coastal salt exposure can accelerate rusting and cause early coating failure if protection depends only on a surface barrier paint.
ZRC Cold Galvanizing Compound is used where corrosion control is required at these vulnerable points, and where steel cannot always be sent for hot-dip galvanizing due to size, logistics, downtime, or site conditions.
How ZRC cold galvanizing compound protects steel
This product is a zinc-rich coating designed for galvanic (cathodic) protection, where zinc acts as a sacrificial metal in close contact with steel. When the coating system is correctly applied on a properly prepared surface, the zinc-rich film helps reduce rust development at scratches, edges, and damaged areas by protecting exposed steel differently from ordinary barrier-only paint systems.
Because it is applied at room temperature as a coating, it is referred to as a cold galvanizing compound. It is commonly used as a specialized galvanizing protection option for fabrication, maintenance, and repair work.
What makes it different from normal anti-corrosion paint
Conventional anti-corrosion paints primarily protect by forming a barrier film that blocks water and air. If that film is damaged at an edge, seam, or impact point, corrosion may start on exposed steel and spread under the coating over time.
ZRC Cold Galvanized Paint is selected when a zinc-rich protective approach is required, especially for steel details where edge protection and repairability matter, such as weldments, fasteners, structural members, railings, supports, platforms, and industrial maintenance zones.
Where it is commonly used
- New steel fabrication requiring galvanizing protection by coating
- Repair and touch-up of damaged galvanized surfaces
- Cut edges, weld seams, drilled holes, bolts, nuts, and fasteners
- Steel structures, frames, brackets, handrails, platforms, and gates
- Industrial equipment and maintenance work where on-site application is needed
Surface preparation and application basics
Performance depends heavily on surface preparation and correct film build. The steel surface should be clean, dry, and free from rust, oil, grease, dust, loose scale, and contaminants. Old, unsound paint should be removed because poor substrate condition can compromise anti-corrosion performance.
- Prepare the surface so it is clean, dry, and contamination-free.
- Remove rust and loose material thoroughly, including at edges and weld areas.
- Apply the coating to properly prepared steel or galvanized surfaces as instructed.
- Build the film thickness to the recommended dry film thickness using the specified coat system.
- Allow proper drying time before handling or returning the part to service.
Practical use notes for project planning
For durability, aim for the recommended dry film thickness and coat count. The stated theoretical coverage is an estimate at a defined film thickness, and actual coverage varies with surface profile, wastage, application method, and jobsite conditions.
For industrial projects, maintenance shutdowns, or fabrication shops, planning quantities and dispatch in advance helps maintain consistent work progress, especially when multiple structures or repair zones are involved.

FAQs
Q: What is ZRC Cold Galvanizing Compound, and how does it protect steel?
ZRC cold galvanizing compound is a zinc-rich coating used for galvanic (sacrificial) protection of steel and ferrous metals. It helps protect steel differently from barrier-only paints by using a zinc-rich dry film for corrosion control when applied to properly prepared surfaces.
Q: What makes ZRC different from normal paint?
Normal anti-corrosion paint mainly works as a barrier coating. ZRC cold galvanizing compound is a zinc-rich system selected for galvanic protection, which is especially useful at edges, weld seams, drilled holes, and repair points where ordinary barrier coatings are more vulnerable after damage.
Q: Does it have a specified zinc content?
Yes. The dry film is specified as 96% zinc by weight.
Q: Can it be used on galvanized surfaces?
Yes, it can be used on properly prepared galvanized surfaces, including repair and touch-up work, provided contaminants and zinc salts are removed and the surface is prepared correctly before application.
Q: Do I need to remove old paint before applying?
Loose, damaged, or unsound old paint should be removed before applying the zinc-rich coating because poor substrate condition can compromise adhesion and anti-corrosion performance.
Q: What surface preparation is required before applying a cold galvanizing compound?
For best results, the surface should be clean, dry, and free from rust, oil, grease, dust, loose scale, and other contaminants. Proper preparation is essential before applying a zinc-rich cold galvanizing compound.
Q: What is the recommended dry film thickness?
The recommended dry film thickness is 80 µm, commonly applied as 40 µm x 2 coats.
Q: How many coats and what film thickness should I aim for?
For durability, apply two coats to reach the recommended dry film thickness of 80 µm (40 µm x 2 coats), unless your approved project specification requires a different system build.
Q: Can it be used in Lahore, Karachi, and coastal environments?
It is used for projects in Pakistan, including inland industrial environments and coastal exposure conditions, subject to correct surface preparation, correct application, and suitable coating system planning for the service environment.
Q: What is the best use case if I can’t send steel for hot-dip galvanizing?
A common use case is on-site protection of fabricated steel, installed structures, large assemblies, and repair work where hot-dip galvanizing is impractical due to size, transport, downtime, or project timeline constraints.
Q: Do you deliver this cold galvanizing compound all over Pakistan?
Yes, nationwide delivery can be arranged across Pakistan, including major cities and industrial areas, subject to courier or transport coverage and order handling requirements.
Q: What is the typical delivery time within Pakistan?
Delivery time depends on the city, courier route, and dispatch timing. Major cities usually receive orders faster, while remote areas may take longer. Confirm the estimated timeline before dispatch for project-critical orders.
Q: How is the product packed for safe delivery?
The product is packed to reduce transit risk, including protection against leakage, dents, and label damage, with handling-focused packaging suitable for courier or transport movement.
Q: Can I order in bulk for industrial projects and get nationwide dispatch?
Yes. Bulk orders can be arranged for industrial customers, fabrication shops, and maintenance projects, with quantity planning and Pakistan-wide dispatch coordination based on project requirements.
