Formed-in strength.

ACCRA logo

ACCRA proprietary form-blow-hardening technology is ideal for producing complex hollow-profile structures that are ultra-strong, yet lightweight.

The ACCRA process:

Boron steel being prepared for ACCRA processing

1. Low cost raw materials
Boron steel tubing is sourced or fabricated in-house, and used as-is or preformed.

Ford Ranger with Multimatic SORB tubes

Multimatic produces over two million SORB tubes per year, including for the North American Ford Ranger.

ACCRA is ideal for:

Jeep Gladiator (JT) with ACCRA Sportbar

Jeep JT (Gladiator) Sport Bar

Roof Structures
Both the the Jeep Wrangler and Gladiator feature an exposed ACCRA Sport Bar — manufactured by Multimatic.

ACCRA structures achieve 1500+ MPa strength and are well-suited for products requiring:


High structural performance (comparable to hot stamping/PHS) within tight packaging constraints


Light weight, without the cost of exotic materials


Closed-section assemblies with no heat-affected zones


Aggressive bends, sweeps or indents with dimensional stability and accuracy over long parts


Variability based on profile cut length
