flame retardant overalls
Comprehensive welding PPE and flame retardant garments for fabrication and welding industries
Designing and manufacturing superior welding PPE clothing, including FR overalls, trousers and jackets, for fabrication, welding, and high-heat environment
leading suppliers of flame retardant overalls
Our heat, flame, and welding coveralls are engineered to protect against intense heat, molten metal splash, and sparks—providing reliable defence in high-risk fabrication and welding environments.
Made with durable, flame-resistant fabrics and compliant with key EN standards, these garments are built for both protection and comfort. Features such as ventilation panels, ergonomic fits, anti-lock zips, and adjustable cuffs support day-long wear, even in physically demanding roles.
We understand that comfort is key to consistent PPE use. That’s why we’re continuously advancing fit, functionality, and fabric performance—including the use of stretch technologies where appropriate to help wearers move freely and safely.
In addition to our stocked range, we also offer custom-made heat and flame solutions, developed in collaboration with large-scale industrial operations to meet specific safety, branding, and operational requirements.

frequently asked questions
It's typically recommended to wear natural fibre garments, such as cotton, underneath flame retardant (FR) overalls, as these do not melt under heat. Synthetic base layers may be unsuitable unless specifically designed for thermal protection. Always follow your organisation’s risk assessments and PPE policy when layering clothing.
FR overalls may need to comply with a range of EN standards depending on the work environment. Common standards include:
- EN ISO 11612 – Protection against heat and flame
- EN ISO 11611 – Protection for welding and allied processes
- EN 1149 – Electrostatic properties
- EN ISO 20471 – High visibility (where relevant)
Always consult the garment’s technical file and ensure it aligns with your operational requirements.
FR overalls are used in a wide range of sectors where workers are exposed to heat, sparks, or molten metal, including:
- Welding and fabrication
- Foundries and metalwork
- Oil, gas, and petrochemical
- Utilities and power generation
- Heavy industry and manufacturing
PPE requirements will vary based on role-specific risk assessments.
The need for FR overalls should be determined by a formal risk assessment that evaluates exposure to heat, flame, molten metal, or similar hazards. If such risks are present, flame retardant PPE may be required as part of your safety control measures.
In general industry terminology, "fire resistant" and "flame resistant" are often used interchangeably. However, it’s most accurate to use "flame resistant (FR)", which refers to garments made from materials that resist ignition and self-extinguish when the heat source is removed. Always look for garments tested and certified to recognised FR standards.
There’s no one-size-fits-all answer. Frequency of replacement depends on the intensity of use, type of exposure, laundering conditions, and the garment's overall condition. Regular inspections are important. If there is visible wear, damage, or contamination that could compromise performance, garments should be withdrawn from use.
Yes. At Alsico, we offer custom-made FR garments that can be tailored to meet the demands of specific tasks or environments. This may include adjustments to garment fit, added features like tool pockets or kneepad compartments, or branding requirements—while maintaining compliance with relevant safety standards.
