Steel Coated Indoors — UK & Europe

Intumescent paint,
applied off-site
and on-site.

SSL Environmental Group coats structural steelwork in our temperature-controlled facility before it ships, and sends spray teams to site for in-place coating, remedials and touch-ups — fire-rated, finished and signed off either way.

Our capability

Everything the steel needs, under one roof.

Full service list →

Intumescent Fire Protection

Thin-film systems sprayed to 30, 60, 90 or 120 minute ratings — cured indoors, measured member by member.

Protective Industrial Finishes

Blast, prime and topcoat packages built around the exposure class your steel will actually live in.

Rail, Bridge & Highways Steel

Sector-compliant paint systems for infrastructure frames, gantries and access structures.

Site Teams & Remedials

Mobile sprayers for damage in transit, erection touch-ups and anything that has to happen on site.

Off-site or on-site?

Choose the right way to coat your steel.

We do both, and many projects use a mix of the two. Here is how to tell which suits your job.

Off-site, in our facility

Best when the steel hasn't been erected yet.

  • New-build frames coming straight from the fabricator
  • Tight site programmes where fire protection would hold up other trades
  • Specs needing controlled heat and humidity to cure
  • Higher fire ratings and thicker coats applied in one controlled run

On-site, by our spray teams

Best when the steel is already in place.

  • Existing buildings, refurbishments and change of use
  • Repairs to damage from transport or erection
  • Connections, welds and touch-ups after the frame goes up
  • Steel too large or fixed to move to a facility

The offsite argument

A controlled booth beats a windy site.

On most steel-frame jobs, fire protection is the trade everyone waits on. Pull it back into a heated facility and the variables disappear: no rain stops, no access clashes, no half-cured coatings. What leaves our doors is finished work, not a job to finish later.

  • Stable heat and humidity, so film build is repeatable
  • Approved applicators across every major intumescent system
  • Wet and dry film readings documented member by member
  • Weeks off the site programme and one less trade to sequence
Who we are
What you gain

Three reasons the steel leaves us finished.

Coating indoors is not just tidier — it changes the programme, the paperwork and the finish your client sees on handover day.

Cured Properly

Heated booths hold the conditions the datasheet asks for, so every coat cures the way it was designed to.

Predictable Dates

Booth slots are booked against your fabrication plan, so deliveries land when the crane is waiting.

Evidence, Not Promises

Film thickness, adhesion and system data travel with the load — ready for the fire engineer.

Step 02

Lock the Slot

Booth time booked against your fabrication dates, with RAMS, ITP and data sheets in your inbox first.

03
Step 03

Spray & Record

Blast, prime, intumescent, topcoat — wet and dry film readings logged for every single member.

Step 04

Load Out

QA pack travels with the load. Steel lands on site cured, protected and ready for the crane.

The verdict from the yard.

"Steel turned up coated, DFTs recorded and paperwork faultless. Took a full trade off our site programme."

Tier 1 Main Contractor
"Fast quoting, honest lead times and a finish our client actually noticed. Exactly what an offsite partner should be."
Fabrication Director

"DFT readings were spot on across the frame and the coating held up through transport and erection with no touch-ups."
