Conventional Dense Castables
Cement-bonded castables for general-purpose linings. Easy to install and forgiving on site.
Low Cement Castables (LCC)
Lower cement content means higher hot strength, lower porosity and better slag resistance.
Ultra-Low Cement Castables (ULCC)
Maximum density and hot strength for severe thermal and mechanical duty.
Self-Flow Castables
Flows around anchors and into complex forms without vibration, for dense, joint-free linings.
Alumina-SiC Castables
Silicon carbide boosts erosion, slag and thermal shock resistance.
Tabular Alumina / Mullite Castables
Tabular alumina or mullite aggregate for high purity, low creep and stable volume.
Abrasion-Resistant Castables
Engineered for cold crushing strength and erosion resistance under particulate flow.
Aluminium-Resistant Castables
Non-wetting additives resist molten aluminium penetration and corundum growth.
Phosphate-Bonded Castables
Phosphate bond gives strong adhesion, early strength and abrasion resistance.
Acid-Resistant Castables
Formulated to resist acid condensate and chemical attack.
Insulating Castables
Lightweight grades that cut heat loss and shell temperature as backup or low-duty hot-face linings.
Dense Gunning Mass
Dry-gunned for fast installation and repair of large areas without formwork.
Shotcrete / Wet-Gunning Castables
Pumped wet and sprayed, giving castable-quality linings with minimal rebound and dust.
High-Alumina Ramming Mass
Rammed in place for dense, crack-resistant monolithic linings.
Plastic Refractories
Mouldable mixes hand-rammed or pounded around anchors, with excellent thermal shock resistance.
Refractory Mortars
Air- and heat-setting mortars matched to every Crown brick grade for strong, tight joints.
Patching & Coating Mixes
Quick repair and protective coatings that extend lining life between relines.
PCPF Shapes
Precast, dried and pre-fired under controlled conditions. They arrive ready to install, so there is no on-site curing.
