Our abrasive blasting and surface preparation services provide high-quality surface treatment for new construction, plant maintenance, refurbishment, protective coating, and corrosion-control applications. We prepare steel structures, tanks, pipelines, vessels, equipment, machinery, and other industrial components to the required surface cleanliness and profile specifications.
Our experienced blasting team carries out internal and external abrasive blasting, removing rust, mill scale, old coatings, corrosion products, dirt, grease, and other contaminants to create a clean, suitably profiled surface ready for protective coating or lining systems. We work to recognized industry standards and specifications, including SSPC/NACE surface preparation requirements, with capabilities ranging from commercial blast cleaning to near-white metal and white metal blast cleaning, depending on project requirements. We carefully control abrasive selection, blasting pressure, surface profile, cleanliness, environmental conditions, and dust contamination to achieve consistent and reliable results.
Our services can include surface inspection, abrasive blasting, surface-profile measurement, dust and soluble-salt testing, visual inspection, and preparation for primer, paint, rubber lining, epoxy lining, and other protective coating systems. Whether it is a single component, pipeline, storage tank, structural steelwork, processing equipment, or complete industrial plant, we deliver professional surface preparation designed to maximize coating adhesion, corrosion protection, service life, and overall equipment performance. From surface preparation to final coating readiness, we provide the quality and technical control required for long lasting protection.
We provide professional rubber lining solutions for pipes, steel plates, tanks, vessels, chutes, launders, and other industrial components exposed to abrasion, corrosion, and chemical attack. Our services include surface preparation, abrasive blasting to the specified standard (e.g., SSPC-SP 10/NACE No. 2 Near-White Metal Blast Cleaning), primer and bonding-system application, precision rubber sheet selection and application, jointing, vulcanization where required, and thorough inspection and testing.
We use high-quality natural and synthetic rubber linings selected according to the operating conditions, including temperature, chemical concentration, abrasion level, pressure, and service environment. All rubber-lined components are inspected for adhesion, thickness, pinholes/holidays, bonding integrity, and workmanship to ensure reliable and long-lasting protection.
