Layer by layer.
Steel shell
Load-bearing outer shell
The steel shell forms the structural envelope of the furnace. It absorbs all mechanical loads and defines the furnace geometry.
Insulation
Thermal insulation layer
The insulation layer minimises heat loss to the outside and protects the steel shell from overheating. Critical for energy efficiency.
Safety lining
Permanent protective lining
The safety lining serves as a fallback level. If the inner layer wears down, it prevents breakthrough to the steel shell.
Wear lining
Working layer in the fire
The wear lining is in direct contact with the molten material. It is regularly renewed during relinings — the core business of SBS.
Ready for operation.
Four layers, one system — each one critical to the safety and service life of your furnace.

Selected projects.
Test furnaces: when the lining measures too
Overhaul of two fire test furnaces: viewing windows and pillars recast monolithically, lower fields in insulating firebricks, insulation and anchors completely renewed.
A chip melting furnace, completely relined
Complete relining of an aluminium chip melting furnace at a premium alloy wheel manufacturer — melting chamber, bath, ramp and pouring spout cast monolithically in one operation.
Relining an ingot casting furnace
Complete relining of an ingot casting furnace at an aluminium plant: old lining broken out down to the steel shell, new insulation layer, anchors, arches cast over timber formwork and openings built to size.
Relining of a Metal Launder
Relining of a launder for molten metal: a tight insulating layer with packed edge joints, anchors in a grid, a steel casing aligned before casting and controlled drying.
Melting chamber with rounded transitions
Relining of a melting chamber in an aluminium plant: wall-to-floor transitions as coves, conically formed openings, monolithically cast and gunned.
General Overhaul of a Low-Pressure Casting Furnace
Complete refurbishment of a low-pressure casting furnace in the workshop: gas-tight sealing faces and penetrations, a dimensionally accurate riser tube seat, non-wetting bath lining.
Circular Furnace Lining in a Lime Works
Bricked ring lining in a furnace shaft of a lime works: brick division calculated for each diameter, annular gap to the furnace shell, surveyed starting ring.

Articles on damage, materials and maintenance — written by the people who know the furnace from the inside.
On site across the DACH region.
From our base in Putzbrunn near Munich, we coordinate projects across the DACH region (Germany, Austria, Switzerland). Our installation teams travel with their own equipment — including special tools, measuring instruments and all required materials. This avoids delays caused by missing logistics and lets us start work straight away.
< 24 h on site
In an emergency, we can be reached around the clock, get back to you within one hour and are usually on site within 24 hours — whether in Hamburg, Vienna or Zurich. Including weekends and public holidays.
In-house installation teams
No subcontractors, no delays. Our permanently employed specialists know every furnace type and work independently on your site.
DE · AT · CH
One point of contact for the entire DACH region. We coordinate travel, materials and installation — you deal with just one contact.
