2559298, 2226528, 2559297, and 2226527 Step Housing components are precision-engineered for SCANIA L-P-G-R-S Series cab access systems. Utilizing high-ductility aluminum alloy (EN AC-46200) with ±0.12mm dimensional accuracy, the design incorporates vortex-reduction contours that decrease aerodynamic drag by 24% during highway operation. Interchangeability with 2559297 left-side assemblies is ensured through standardized mounting interfaces, while the patent-pending drainage system prevents debris accumulation in off-road conditions. Multi-stage surface treatment combines micro-arc oxidation (MAO) coating with ceramic-impregnated polymer layers, achieving 1500+ hour salt fog resistance per ISO 9227 NSS testing protocols.
