Ignoring Concrete Strength
Anchor performance depends on the strength and condition of the concrete foundation.
Always follow the minimum concrete requirements specified by the design engineer.
Choosing the Wrong Surface Finish
Indoor coatings should not be used for outdoor transformer yards or corrosive industrial environments.
Incorrect Hole Preparation
Proper hole diameter, drilling depth and cleaning are important for achieving reliable anchoring performance.
Always follow the installation instructions and project specifications.
Buying Only on Price
The lowest-cost anchor bolt may not provide consistent dimensions, reliable material quality or adequate corrosion protection.
