DOCO International Ltd is one of the leading suppliers of sectional door hardware in Europe, with a reputation for providing good quality components at very competitive prices. Everyone knows that, but not everyone knows the company offers shot blasted industrial door springs. What is a shot blasted spring? Shot blasting (also known as shot peening) involves blasting the spring with hundreds of steel ball bearings to smooth the surface of the coil. This eliminates any microscopic cracks and tears and gives the finished product a range of benefits, such as: • Significantly improving the mechanical properties of the spring • Allowing for lighter weight spring designs without losing power output • Increasing the fatigue strength of the spring by between 20% and 100% • Compensating for manufacturing-related surface defects • Significantly extending the stress-load limit of the spring And, with DOCO International Ltd, all this comes at a comparable price to an ordinary black spring of the same power. The company stocks a large range of the most common spring sizes used in the UK, all deliverable within 24 – 48 hours - to either your premises or directly to your engineers on-site. If you don’t know what size you need, simply use the comprehensive spring calculation tool at www.doco- international.co.uk/en/support/spring-calculator/spring- calculator-general.html. Provide the width, height, weight and type of door system and the tool will provide two or more spring solutions. Call the DOCO service team on 01904 607869 with the above information for a quick calculation and price. You can also enquire about other repair-related products, such as spring break devices, cable break devices, rollers, hinges and aircraft cable.
