Strata Worldwide was founded on its line of engineered secondary roof supports for underground mining. We offer options in timber, steel and concrete. With qualified product specialists we can understand your requirements and recommend the best solution for your mine.
Timber standing prop support with a built-in yield-zone
The yield-zone enables safe deformation under load, preventing buckling and breaking
Simple timber support with improved materials handling and fast installed support
Power Wedge, a mechanical pre-stressing device, fits onto Propsetter to apply active pre-loading up to 10 US tons
High-capacity, interlocking timber blocks stacked in layers floor-to roof
Engineered notches create 100% contact between layers, significantly increasing strength and stability
Available in 2-and 3-notch options. The longer the blocks, the stronger and more stable the support system. Ideal for areas exceeding 10 feet (3m)
100% contact uses 50% less timber for the same support capacity as competitor products
High-capacity, high yielding timber standing support prop, formed by bundling three Strata Propsetters and binding with pre-tensioned metal straps
Available in lengths up to 10ft (3m) and in three load capacities: 100 to 250 US tons
Offers up to 16in (400mm) of stable deformation for unmatched safety
Specialized system bundling for optimized transport and handling. Improves haulage productivity up to 70% compared to comparable support capacity roof supports
Compact mechanical steel prop that provides active support using hydraulic pre-loading and safe yielding under load
Countless applications in all types of mining and underground construction. Can be installed vertically, horizontally or at an angle
Extends hydraulically to roof height and applies active pre-load for enhanced performance. Suitable for heights up to 60ft (6m)
High load-bearing capabilities and stable yield make it suitable for high closure and seismic mining environments
Ultra-compact, self-contained steel prop that can be installed by one person
Consistent 60 US ton support with 2 inch controlled deformation
Engineered adjustability. Each prop offers 2 feet of height extension
Fast, immediate support installable by one person. Optimal handling, no tools or equipment required
E.Dillon patented high capacity circular concrete supports
Cut-able fiber reinforced concrete ideal for longwall moves, or for permanent, non-degradable roof support
Stacked in layers, blocks provide dimensional stability, increased strength and stable yielding for active ground conditions
Cribpacs® are pre-packaged stacks of 4, 5 and 6 layers with plywood for yielding and easier mechanical handling
E.Dillon patented high capacity concrete supports
Cut-able fiber reinforced concrete ideal for pre-driven recovery rooms, or permanent, non-degradable roof support
Stacked in layers blocks provide dimensional stability, increased strength and stable yielding for active ground conditions
CribStacs® are 24” x 24” pre-bundled stacks with plywood for yielding and easier mechanical handling
