Solar Projects


We are the leading fastener and component suppliers to Solar Plant Manufacturer. we have wide range of products as per requirements.

Solar Construction needs fasteners it can rely on during heavy construction, in outdoor environments, and under other conditions that demand high-quality. Fasteners we provide mostly like foundation bolts, Anchor bolts, Hex bolts & nuts.

  • We are your one-stop source for non-standard fasteners cut to length and threaded to your exact application specifications. Our extensive inventory includes blanks in many grades of steel. We carry Hex Bolts up to 4" / M100 in diameter and 48" long, as well as Heavy Hex Nuts up to 4" / M100 in diameter.
  • We can make fasteners as per your requirements because we have in house forging capacity of M100 bolts manufacturing with high precision CNC machining.

Types of Fasteners used in Solar Projects Construction

  • Spiralock Nuts
  • Hex Bolts & Nuts
  • Allen Bolts
  • Square Nut
  • Anchor Bolts
  • Avbolt Lockbolts
  • Stud Bolts
  • Monobolt Rivets
  • Hemlok Rivets
  • Foundation bolts etc

Fasteners are bolts, nuts, washers, and a few screws. Those fasteners are intended to make an impermanent relationship between two items. This temporary association implies you can eliminate these latches without making harm to the assembly. Rivets, welds, lockbolts, and a few screws are viewed as Permanent fasteners, intended to make an extremely durable gathering between two items. This truly intends that assuming you eliminate one of these clasps, you'll make harm the association. The right fastener will be directed by the design of the solar system.

Since these Solar Projects are subject to extreme weather conditions, exposed to weather, and in contact with harsh environment, the protective coatings that Roll-Fast can apply to the fasteners are particularly important. These include the Hot Dip Galvanized, Zinc Plating, Geomat with the addition of the topcoat.

At Roll-fast, we have a wide range of fasteners which are suitable for this very need. As a leading supplier of Hex Bolt, double end stud bolts and hex nuts, our fasteners conform to the strictest ANSI, ASME, BS, European, IS and ISO standards for ideal use in the harsh environments of the Solar Projects Construction.

We can provide you Carbon Steel, Alloy Steel, Stainless Steel, Aluminium, Brass, Silicon Bronze Fasteners as per size or drawing you need.
