Structural Bolts - FAQs

Structural Bolts are heavy-duty bolts designed for use in structural connections. Unlike regular bolts, they are engineered to bear high loads, making them ideal for critical applications like building frames and bridges. They adhere to specific industry standards and undergo rigorous testing to ensure reliability and safety.

Choosing the right Structural Bolts involves considering factors like load requirements, environmental conditions, and the type of connection. Consulting with structural engineers or reaching out to our experts at GIC Fasteners can help you determine the appropriate bolt type, size, and material for your specific project needs.

Yes, Structural Bolts can be coated with materials like zinc, hot-dip galvanizing, or made from stainless steel to enhance their corrosion resistance. These coatings protect the bolts from rust and corrosion, ensuring their longevity even in challenging environments.

Absolutely, Structural Bolts are commonly used in outdoor applications, including bridges and outdoor structures. Proper coatings and materials make them resistant to weather elements, ensuring their reliability and stability in various outdoor settings.

Structural Bolts are typically designed for single-use applications to maintain their integrity and strength. Reusing these bolts might compromise their structural integrity, leading to potential safety hazards. It's advisable to use new bolts for each installation to ensure optimal performance.

A325 and A490 are two common grades of Structural Bolts, with A490 having a higher tensile strength than A325. The choice between the two depends on the specific load requirements of the project. A490 bolts are used in applications where higher strength is necessary, while A325 bolts are suitable for standard structural connections.

Yes, Structural Bolts can be used in seismic applications, provided they meet the seismic specifications outlined in the building codes. These bolts, when properly installed and chosen according to seismic requirements, contribute to the structural integrity of buildings during seismic events.

Proper installation of Structural Bolts is critical for their performance. It involves ensuring the correct torque values, using the appropriate washers and nuts, and following the guidelines specified in the installation manual. It's advisable to have a qualified professional oversee the installation process to guarantee the bolts' reliability.

For top-quality Structural Bolts that meet industry standards and offer exceptional reliability, trust GIC Fasteners.
