Range of GI Foundation Bolts

L-Type GI Foundation Bolts

R. G. International manufactures high-strength L-type GI foundation bolts designed to provide secure anchorage for structural columns, poles, machinery bases, and steel frameworks. The characteristic L-shaped bend at the embedded end ensures excellent mechanical interlock within concrete foundations, offering high resistance to pull-out forces and vibration. These foundation bolts are widely used in transmission structures, substations, industrial sheds, and infrastructure projects where long-term structural stability is critical.

J-Type GI Foundation Bolts

Our J-type GI foundation bolts are engineered for heavy-duty anchoring applications that demand enhanced load-bearing capacity and secure embedment. The curved J-shaped configuration provides superior anchorage compared to straight bolts, making them suitable for power plants, heavy equipment foundations, solar structures, and transmission tower bases. Manufactured from IS: 2062 compliant steel and hot-dip galvanized, these bolts deliver durability and corrosion resistance even in harsh operating environments.

Straight Anchor Bolts with Plate Washers

R. G. International supplies straight GI anchor bolts with plate washers, offering flexibility in alignment and precise positioning during installation. The addition of heavy-duty plate washers enhances load distribution and improves anchoring strength within concrete foundations. These anchor bolts are commonly used in structural steel connections, machinery installation, base plate fixing, and retrofit applications where accuracy and adjustability are essential.

Plate Type GI Foundation Bolts (Plate Welded)

We manufacture plate type GI foundation bolts featuring welded anchor plates at the embedded end for superior load transfer and anchorage. These plate-welded foundation bolts are ideal for applications involving heavy static and dynamic loads, such as industrial machinery foundations, power plant structures, and large steel frameworks. The welded plate design ensures uniform stress distribution within the concrete, significantly reducing the risk of pull-out or failure.

GI Sleeve Anchor Bolts

Our GI sleeve anchor bolts are designed for post-installed anchoring solutions in concrete and masonry substrates. These bolts expand within the drilled hole when tightened, creating a strong and reliable hold without the need for pre-cast embedment. Sleeve anchor bolts are widely used for secondary structural supports, equipment mounting, handrails, and retrofitting applications where flexibility and ease of installation are required.

GI Eye Foundation Bolts

R. G. International manufactures GI eye foundation bolts used for lifting, rigging, and securing cables, chains, or structural components. Designed for strength and safety, these eye bolts are fabricated with precision and hot-dip galvanized to ensure long service life and corrosion resistance. They are commonly used in industrial plants, infrastructure projects, and maintenance applications where secure anchoring and lifting points are essential.

Applications of GI Foundation Bolts

• Power Transmission & Distribution Structures
• Substations & Switchyards
