About Us

SDPI offers a clear value proposition to both industry stakeholders and member businesses. For clients, main contractors, and specifiers, the index provides reassurance that listed companies operate to recognised standards, maintain appropriate processes, and demonstrate a commitment to best practice. This reduces risk in procurement and supports informed decision-making, particularly on complex, high-value, or regulated projects.

For member businesses, SDPI functions as a strategic growth platform. Inclusion on the index enhances credibility, strengthens tender submissions, and improves visibility within the structural steel supply chain. Membership also supports access to industry networks, technical guidance, regulatory insight, and professional development opportunities, helping businesses remain competitive and compliant in a changing market.

By raising standards and improving transparency across the sector, SDPI supports higher-quality project outcomes while enabling steel detailing businesses to differentiate themselves, secure more demanding work, and build long-term, sustainable operations.
