Project Specifications
Most industrial jobs are specified by an engineer or the coating manufacturer. A clear specification makes quotes comparable. Include:
- The cleanliness standard required, for example Sa 2½ (near-white) under ISO 8501-1.
- The surface profile needed for the coating, in microns.
- The coating system that follows, and how soon after blasting it must go on.
- Inspection and hold points, and who signs off each stage.
If there is no specification, ask the coating supplier. Blasting and coating are usually best quoted together so one contractor answers for adhesion.
Scheduling Around Operations
- Shutdowns and weekends are common. Say when equipment is available.
- Site induction, permits and safety files take time. Mention them up front.
- Nearby production lines, motors and bearings need sealing against dust.
- Confined spaces such as tank interiors need specific permits and equipment.
Limitations and Preparation
- Oil and grease must be removed before blasting, or they get driven into the surface.
- Old lead-based or other hazardous coatings need testing and controlled removal.
- Thin sheet and precision surfaces may need a gentler media or masking.
- Blasted steel must be coated before it flash rusts, especially near the coast.

Ballpark figures, not quotations. Compiled from price guides and price lists published on South African websites (published between April 2025 and January 2026, plus one undated powder-coating price list: a metal-painting price guide, an industrial coating price list and a powder-coater's indicative list), checked 13 October 2026 and rounded. Most are national or Gauteng guides, so Cape Town quotes can differ. Unless a row says so, the sources do not state whether VAT is included, so confirm VAT on every quote. Photos, an inspection and a written quote set the actual price.
What Affects an Industrial Quote
- Square metres of steel and its shape: flat plate is quicker than lattice or pipe.
- Required cleanliness standard and profile.
- Access: scaffolding, lifts, rope access or confined space.
- Containment, shutdown windows and after-hours work.
- Coating system, number of coats and inspection.
- Waste disposal, especially for hazardous old coatings.
What to Send With Your Request
- The specification or coating system, if you have one.
- Drawings, steel lists or rough square metres.
- Photos of the current condition.
- Site rules, induction and permit requirements.
- Available dates and shutdown windows.

Frequently Asked Questions
What does Sa 2½ mean?
It is a visual cleanliness grade in ISO 8501-1, often called near-white blast. Most mill scale, rust and old paint is removed, leaving only slight staining. Many coating systems call for it.
Can blasting be done during production?
Sometimes, with screening and sealing of nearby equipment. Dust-sensitive areas usually need a shutdown or after-hours work.
Should blasting and coating be quoted together?
It is usually simpler. If one contractor does both, there is no argument about whether a coating failure came from the preparation or the paint.
Can tank interiors be blasted?
Yes, by contractors equipped for confined spaces, with ventilation, permits and a standby person.
What happens to old lead-based paint?
It must be tested and removed under controls, with proper waste handling. Tell contractors if the coating is old or unknown.
