Cleanroom anti-fatigue Welding mats, Ergomat Softline. The Softline is designed for areas where resistance to oil, acids, petrochemical and heat is an important requirement, making it an ideal ergonomic mat for welding and metalwork. In situations with excessive fluid volume, or the need to promote air flow, Softline can be die-cut to accommodate these requirements. Softline is available in three colors to facilitate protection against cross contamination hazards. The Softline is also resistant to many acids, as well as hot metal shavings (spark resistant) with brief exposures up to 600?C (1112?F). Most recommended Weld Mat in the industry.
