Strata Products™ - Underground Mining Roof Support Products

Strata Products (USA) develops high quality but cost-efficient roof support products for underground mines. We have a range of products that can be used on rib, roof and floor control as well as longwall shield recovery screens.

Since being established in the US in 1992, Strata Products has expanded internationally to include active operations and manufacturing facilities in the UK, Poland and Australia.

Rocprop™ Mechanical Roof Prop

Rocprop, imported and distributed exclusively by Strata Products is a leader in underground mining roof support products. It is a compact roof prop that offers active support by using hydraulic pre-stressing.

Strata Products sells hundreds of Rocprops monthly to mines across the US, UK and Australia. Rocprop is the prop of choice due to its superior performance at greater heights, unique pre-loading abilities, quick and easy installation and significant reduction in transportation costs and time. Rocprop is an active support, which means it applies an upward force on the roof, pushing the layers of strata up and together while it supports. It also has a controlled yielding ability to up to 30% of its initial height.

Propsetters - Yielding Roof Control in Underground Mines

Finding an effective support system that can handle the high deformation of tailgate environments is an issue for all longwall miners. Strata Products introduced the Propsetter Support System to meet this need while at the same time introduced one of the most cost-effective support prop available.

The Propsetter is a specifically designed timber prop with yielding capabilities, support capacities that match four-point cribs and superior handling and transportation abilities. They are used predominantly in tailgate support but are also very effective in longwall shield recovery and long-term bleeder support.

Propsetters are actively installed in mine around the US, UK and Australia.

Cluster Prop - High Capacity Support System

Strata Products has recently developed the innovative Cluster Prop to meet the market demand for a higher capacity support system without the bulk of a crib. This product is a set of three Propsetters bundled together creating a combined yield strength of more than three times that of the individual Propsetter, including the benefit of added stability.

Sand Prop - Re-Usable Roof Support System

Sand Prop is Strata Products' re-usable roof support system. Designed and manufactured by Strata Products, this simple yet effective secondary roof support can be installed in minutes by a single person. Its fast and easy installation requires no specialized tools. Exposure time on longwall moves and longwall shield recovery is cut in half due to the speed of installation and the immediate support offered by the Sand Prop. The narrow diameter and steel construction of the props reduces ventilation resistance and makes them very useful in beltline entries and intake and return escape routes.

In addition to being used for longwall moves, shield recoveries, beltline entries and escape routes, Sand Prop is very effective at providing additional support and protection to permanent seals. The Sand Props are installed behind and in front of the seals to provide extra support and protect them from roof falls.

Link-N-Lock - Crib Replacement System

Link-N-Lock is a crib replacement system with interlocking timber blocks that stack in layers. Their interlocking abilities provide 100% contact between layers which maximizes timber efficiency and increases strength and stability. Link-N-Lock can be installed to heights greater than conventional cribbing systems.

Each Link-N-Lock is smaller, lighter and easier to handle than conventional crib blocks, which results in significant savings in material handling, productivity, labor and transport.
