Anyone who has worked on a petrochemical or LNG project will recognize the situation: the control room needs blast protection, the site is tight, and the schedule is already under pressure. Reinforced concrete is the usual answer, and it does the job - but it is heavy, slow to cast, and awkward to fit into retrofit work or confined plant layouts. That is usually when the conversation turns to panel systems.
What Actually Drives the Choice
Most specifiers end up weighing the same handful of things. Blast performance comes first, and it needs to be backed by real test data rather than a theoretical calculation. Fire resistance matters too, especially where the wall also serves as a fire compartment boundary. After that come the practical issues: how much the panel weighs, how it connects to the primary structure, whether it will hold up in a corrosive environment, and what maintenance looks like over a 20-year horizon.
One option that has found use in petrochemical plants, power stations, LNG stations, and hazardous material warehouses is the fiber cement composite steel panel. The construction is fairly straightforward: a high-density reinforced fiber cement core, hot-dip galvanized steel plates on both faces, bonded under high pressure.
Typical specifications:
Fire resistance: up to 4 hours
Standard size: 1200 × 2400 mm
Thickness: 9.5 mm
Steel thickness: 3–5 mm, customizable
In practice, a standard panel can be handled and installed by one person, which keeps transport and labor costs down. The panels can be cut and drilled with ordinary tools, so curved walls and irregular openings are less of a problem than they are with precast concrete. Common applications include blast-resistant walls, ceilings, and partitions.
