Key Features & Benefits

100% Cotton Bizweld Fabric The Bizweld fabric is made from 100% ringspun cotton yarns, offering exceptional pilling resistance while guaranteeing comfort, warmth, and protection. Cotton is naturally breathable and feels comfortable against the skin during long working hours – a significant advantage over synthetic FR materials.

Multi-Standard Flame Resistant Protection This jacket provides comprehensive protection against multiple heat hazards, including radiant heat, convective heat, contact heat, and molten metal splash. The flame resistant finish ensures the fabric self-extinguishes when the ignition source is removed, protecting the wearer from ongoing burn injuries.

Welding Industry Certified Meeting EN ISO 11611 Class 1, this jacket is specifically designed and tested for welding and allied processes. The certification covers protection against small splashes of molten metal, short contact time with flame, radiant heat, and UV radiation from the electric arc.

Arc Flash Protection With IEC 61482-2 certification and an ATPV rating of 11.2 CAL/CM² (HAF 80.4%), this jacket provides essential protection for workers exposed to electric arc hazards. The ELIM rating of 8.3 CAL/CM² indicates the incident energy level below which no second-degree burn would be expected.

Practical Design Features The jacket includes secure stud fasteners down the front for easy donning and doffing, two chest pockets with flap closures for secure storage, stud adjustable cuffs for a personalised fit, a concealed mobile phone pocket, and a radio loop for convenient communication device attachment.

Clear Safety Labelling External labelling clearly shows all certified standards the garment has achieved, ensuring the protection level of the wearer is easily identifiable in the workplace – essential for site safety compliance.

Durable Construction At 330gsm, the Bizweld fabric provides substantial protection while maintaining flexibility and comfort. The quality construction withstands the demands of heavy industrial use and maintains its protective properties through repeated washing.
