McNish Steel manufactures stud rails for projects requiring efficient, engineered punching shear reinforcement in flat concrete slabs. Our McNish PSR Rails™ are designed to improve performance at column-to-slab connections by increasing punching shear capacity while helping reduce reinforcement congestion and simplify installation. Built to demanding quality standards, our stud rails provide a practical solution for commercial, industrial, and infrastructure concrete construction where strength, efficiency, and coordination all matter.

McNish PSR Rails™ are engineered punching shear reinforcement systems used in flat concrete slabs and foundation slabs. The system consists of large-headed shear studs stud-welded to flat steel bars, forming stud rails that help resist punching shear stresses at column-to-slab connections. By extending the effective column perimeter into the slab, stud rails support improved load transfer and more efficient reinforcement layouts in critical areas of the structure.
Stud rails are often used in place of more traditional reinforcement approaches where project teams are looking to reduce congestion, improve constructability, and support cleaner slab designs. At McNish Steel, our stud rails are manufactured to meet engineered project requirements and are built for dependable performance in demanding concrete applications.
McNish Steel’s stud rails are manufactured using PSR studs of predetermined lengths and diameters to meet project-specific engineered requirements. Our production processes are designed to maintain quality, consistency, and compliance with recognized structural welding and product standards.
Standards & Certifications
These standards help ensure that McNish PSR Rails™ are produced to a high level of quality and reliability for structural concrete applications. Where required, product configurations can be aligned with engineered slab and foundation designs.
Stud rails are used to reinforce flat slabs and foundation slabs in areas where punching shear resistance is critical, particularly around columns. Their design helps distribute forces over a larger critical shear perimeter while reducing reinforcement congestion at the column connection. This can make installation faster, simplify site setup, and improve coordination in areas that are often heavily reinforced.
Depending on project design requirements, stud rails can also help reduce or eliminate the need for traditional reinforcement measures such as column capitals, shear stirrups, or drop panels. By increasing punching shear capacity at the base of concrete columns, they may also support thinner, more efficient slab designs. The result is a reinforcing solution that can improve constructability, reduce labour demands, and support better overall slab performance.

Clients choose McNish Steel for stud rails because we combine reinforcing steel expertise, certified fabrication quality, and a practical understanding of concrete construction demands. We know that products used in critical slab connection areas must be manufactured with consistency, backed by strong quality controls, and delivered in a way that supports efficient project execution.
As a family-owned company with decades of experience in reinforcing steel, McNish Steel provides stud rail solutions backed by responsive service, dependable manufacturing, and a strong commitment to quality. Our goal is to help project teams source engineered reinforcement systems that improve performance while making installation more manageable in the field.
