Cleaner. Faster. Safer. Smarter.
When it comes to restoring structural steel, laser cleaning isn’t just an upgrade, it’s a revolution. And Sentinel is the only contractor in the UK currently offering this precision-engineered service at scale.
In a construction world moving fast towards Net Zero and circular economy principles, the way we treat steel during refurbishment has a big impact, not just on environmental performance, but also on programme, safety, and compliance.
The Smarter Way to Prepare Steel
Sentinel’s laser cleaning delivers:
• Zero substrate damage – preserves the integrity of underlying steel
• Pinpoint precision – ideal for localised or selective treatments
• Minimal disruption – quieter, cleaner, and faster on live or sensitive sites
• Sustainable results – 90% less waste and significant CO₂e savings
• Safe for operators – no manual abrasion, no HAVS, no blasting dust
On a recent refurbishment project, in partnership with LaserTec UK, we laser-treated 18,000 m² of steelwork. The results speak volumes:
• Waste cut by 100%, from a potential 236 tonnes down to ZERO
• 257,000 kg CO₂e saved – the same as taking 56 cars off the road for a year, or avoiding 156 London–New York flights.
Cleaner. Faster. Safer. Smarter. When it comes to restoring structural steel, laser cleaning isn’t just an upgrade, it’s a revolution. And Sentinel is the only contractor in the UK currently offering this precision-engineered service at scale.
