The new-model slag block 40x20x20 is a standard-format masonry unit of 400x200x200 mm, produced by vibro-pressing a mixture of cement binder and slag aggregate. Slag blocks remain one of the most cost-efficient walling materials available: at roughly $0.18 per block, a square metre of wall costs a fraction of brick equivalents, while the large format lays around four times faster than standard brick — twelve and a half blocks replace a square metre of wall that would otherwise demand dozens of bricks and proportionally more mortar and labour.
The 200 mm width produces a structural wall in a single course for low-rise construction, outbuildings, garages, fences and industrial enclosures. Slag aggregate also gives the blocks useful thermal mass and sound damping compared with dense concrete.
The 10,000-piece minimum order corresponds to a few truckloads — the scale at which building-materials traders, construction companies and developers buy walling. For export buyers in regions with active low-rise and utility construction, commodity masonry blocks are a steady-volume product whose economics hinge on production cost, which is exactly where factory-direct Russian supply is competitive.
