Who we are
McClay Industries sources and supplies concrete technologies that change how structures are designed and built in Australia — then stays on the job to make sure they perform.
SteelX is the reinforcement side of that work: twisted steel that mixes straight into the concrete, replacing mesh and bar with something safer, faster and stronger. McClay also supplies E5 Nano-silica for internal curing.
