Hardwood sleepers for rail, mining, and heavy infrastructure.
We supply sustainably sourced Erythrophleum SPP (Missanda) hardwood sleepers. Available as virgin timber or creosote-treated for open tracks, bridges, turnouts, and underground structural support.
Supply Capabilities
Erythrophleum SPP (Messanda / Missanda).
Sisanda Agric restricts sleeper manufacturing exclusively to high-density African hardwood species. Over the years, we have established solid relationships with timber farmers locally and internationally to secure sustainable volumes of Messanda/Missanda hardwood.
This specific species provides the necessary bending, shear, and compressive strength required to distribute forces exerted from the rail directly into the track substructure.
Heavy-duty operational thresholds.
In the normal functioning of a rail track, a sleeper must retain strength properties over its expected lifespan. Our sleepers are engineered to maintain an effective bearing surface, holding rails securely to maintain gauge and inclination.
Stock, treatment, and loading.
Visual confirmation of our sleeper stock, from raw virgin Missanda timber to fully creosoted sleepers ready for infrastructure dispatch.
Choose the right timber finish.
We supply both untreated stock for custom infrastructure applications and fully treated sleepers for immediate railway deployment.
Treated (Creosoted) Sleepers
Hardwood pressure-treated with creosote to SANS/AWPA standards, providing maximum resistance to moisture, rot, and ground contact deterioration.
Virgin Hardwood Sleepers
Raw, high-density untreated hardwood supplied for projects that manage their own treatment or require pure structural timber strength.
Standard dimensions & tolerances.
Our hardwood sleepers are cut to precise SABS tolerances to support standard open track, turnout crossings, and steel-decked bridges.
