Repair without welding.
Protect without replacement.
Belzona polymeric repair composites and protective coatings — specified, supplied and applied across Bangladesh by S.A. International’s Belzona-trained engineers since 1999.
Why Belzona
The cold-applied alternative to hot work.
Belzona systems rebuild worn metal, seal live leaks and line eroded equipment — with no welding, no naked flame and no heavy lifting. Most repairs are completed in-situ during a normal maintenance window, returning plant to service in hours instead of weeks.
- 01No hot work permit requiredCold-curing polymers eliminate weld distortion, fire risk and post-weld inspection.
- 02Applied in-situ, even onlineSurface-tolerant grades cure on damp, oily or live leaking surfaces.
- 03Outlasts the original surfaceCeramic-filled barriers resist erosion-corrosion better than the parent metal.
- 04Backed by Product PlusSpecification, on-site supervision and inspection from our trained engineers.
The Belzona range
Five families. Every failure mode covered.
Each series targets a class of maintenance problem — from rebuilding worn shafts to lining chemical tanks.
Metal Repair & Protection
Paste-grade composites and ceramic barrier coatings that rebuild worn pumps, shafts, valves and heat exchangers.
Explore 1000 Series →Elastomers — Rubber Repair
Resilient urethane systems that repair and recast rubber components: impellers, conveyor belts, expansion joints.
Explore 2000 Series →Roof & Weatherproofing
Microfibre-reinforced flexible membranes that seal roofs, cladding and lagging — applied cold, even to damp surfaces.
Explore 3000 Series →Concrete & Chemical Protection
Granite-hard concrete repair mortars, chemical-resistant coatings for bunds and containment, and anti-slip floor systems.
Explore 4000 Series →Coatings & Linings
High-performance barrier coatings for immersed and atmospheric service — tank linings, cooling water systems.
Explore 5000 Series →Specialist Systems
Condenser brush systems, sealing compounds, release agents and specialist maintenance products outside the core 5 families.

You buy more than a polymer.
Belzona’s “Product Plus” philosophy means every product is delivered with engineering. As the authorized distributor, S.A. International carries that service through to your plant floor.
Problem diagnosis & specification
On-site survey of the failure, followed by a written Belzona specification — product, surface preparation and application method.
Genuine supply, locally stocked
Factory-fresh Belzona from the UK, with batch traceability and technical data sheets for every pack.
Trained application crews
Belzona-trained applicators execute the repair — surface preparation, mixing, application and curing controls.
Inspection & aftercare
Post-application inspection, documentation and follow-up — so the repair performs for years, not months.
