BlastOne’s comprehensive Surface Areas of Angles guide is an invaluable resource for blast cleaning and painting professionals. This detailed reference provides precise surface area calculations for both equal and unequal angle profiles, enabling accurate material estimation and project planning. Our extensive tables cover a wide range of nominal leg sizes and thicknesses, offering surface area measurements per metre and per tonne. Whether you’re working with 200x200mm equal angles or 150x100mm unequal angles, this guide ensures you have the exact data needed to optimize your blasting and coating processes. By utilizing this information, contractors can improve efficiency, reduce waste, and enhance the accuracy of their project quotes.
