SELP – Foundation bolt

SELP foundation bolts are foundation bolts that are installed in concrete before it hardens, they transfer forces from structures to the foundation column or foundation. SELP foundation bolts are designed for more robust connection solutions and larger bolt sizes.

How do SELP foundation bolts work?

SELP foundation bolts are installed in the concrete structure before the concrete hardens, they transfer forces from the structure to the foundation column or foundation.

The bolts are anchored using a rebar (SELP/P) or an anchor plate (SELP/L).

How are different models of SELP foundation bolts used?

Short foundation bolts SELP/L are used in shallow column foundations, concrete element connections and machine and equipment foundations.

Long foundation bolts SELP/P are used in the aforementioned objects and as joints when reinforcing columns.

Materials and sizes

The foundation bolts are made of round bars, the material is structural steel. The anchors are made of rebars, class B500B.

Alternative

Black steel without hot-dip galvanizing: SELP/L or SELP/P
Black steel with hot-dip galvanization: SELP/L KZN or SELP/P KZN

SELP foundation bolts are manufactured in sizes M27–M52.

Note: The bolt delivery also includes washers and fastening nuts (2 pcs/bolt). SUJ foundation bolts are also available bent. In addition to the bolts, a mounting frame is available, which facilitates the installation of the bolts in place.

Manufacturing

The products are manufactured in an EN 1090 certified workshop. Bolted parts and anchors are manufactured according to measurements, and the weld joints on the anchor plates are performed using robotic welding or manual MIG welding.The welding class for the joints is C according to the SFS-EN ISO 5817 standard.
