IEQSA counts on a modern laboratory to support all its production and quality control activities. Our chemical analyses are made both by atomic emission and atomic absorption, both internationally known and trustworthy methods. We count on our own equipment to measure the specific surface area of our zinc oxide. We own a well developed laboratory for metallurgical tests for rolled zinc products, allowing us to control characteristics such as: specific temper, deep-drawing capability, fluency, resistance to traction, bending quality and metal fatigue from alternate bending.
