Cooperation Between Parsin Industrial Supplies Sepahan and EPC Companies in Supplying Bolts, Nuts, and Gratings for Large-Scale Industrial Projects

Introduction

In large-scale industrial projects especially in oil, gas, petrochemical, power plant, and steel industries—the role of EPC companies (Engineering, Procurement, and Construction) is crucial. These companies, as the main contractors of national and international projects, rely heavily on accurate, timely, and standard-compliant procurement of industrial components and materials. Among the most essential consumable items are high-grade bolts and nuts and industrial gratings, which are widely used in structures, piping systems, platforms, and access walkways.

In this context, Parsin Industrial Supplies Sepahan, with over a decade of specialized experience in supplying and manufacturing these components, has become a trusted supplier to many prominent EPC companies across Iran.

The Importance of Bolts, Nuts, and Gratings in EPC Projects

Although bolts and nuts may seem small in size, they play a vital role in ensuring the integrity, safety, and durability of industrial structures. The correct selection of material grade, proper surface coating (such as hot-dip galvanizing or Dacromet), threading standards (UNC, UNF, Metric, etc.), and strict quality control are all critical in EPC project success.

Likewise, gratings serve a functional role in flooring of industrial structures, maintenance platforms, walkways, and offshore facilities. Whether steel or FRP (fiberglass), gratings must offer high load capacity, dimensional precision, and resistance to corrosive environments—especially in petrochemical and marine applications.
