Carbon Steel Foundation Bolts DIN 529(A)
Product Overview
Carbon steel foundation bolts are essential anchoring components used to secure structures to concrete foundations. Designed according to DIN 529(A) standards, these bolts provide a reliable connection between structural elements and their concrete base. With their L-bent or straight shaft design and embedded ends, foundation bolts are commonly used in heavy industrial, civil, and commercial construction projects where stability, load-bearing capacity, and long-term performance are crucial.

Material Description & Manufacturing Process
The primary material used is low to medium carbon steel, known for its excellent machinability, weldability, and cost-effectiveness. Foundation bolts are manufactured through the following process:
Material Cutting – Raw carbon steel bars are cut to length.
Bending/Forming – L-bends are formed as per DIN529(A) requirements.
Threading – Threads are rolled or cut to precise tolerances.
Heat Treatment – Improves mechanical strength and durability.
Surface Coating – Zinc plating or hot-dip galvanizing enhances corrosion resistance.
Inspection – Dimensional and mechanical checks ensure product quality.
Typical Applications in Key Industries
Carbon steel foundation bolts are commonly used in:
Construction Industry: For anchoring steel structures, columns, and support beams.
Wind & Solar Energy: Fixing turbine towers and photovoltaic systems.
Oil & Gas: Mounting heavy equipment on platforms.
