Japanese steelmaker JFE Steel has announced that it has developed the JFE fire-resistant coating reductionmethod, a construction technique that reduces the thickness of fire-resistant coatings on H-shaped steel beamsby up to around 40 percent compared with conventional approaches.
The method was developed in response to increasing pressure on the construction sector from labor shortagesand rising material costs, which have driven demand for more efficient and rational building solutions. Efficiency and space gains in construction
By lowering the required thickness of fire-resistantcoatings, the new method allows finished column and beam dimensions to be reduced. This increases usable interior space while also cutting installation labor andoverall construction costs. JFE stated that the approachhas already been applied in a wide range of building projects.
1.5-hour fire-resistance certification secured
Following customer demand to extend the coating reduction concept beyond steel pipe columns,JFE has now obtained a new 1.5-hour fire-resistance certification
specifically for H-shaped steel beams.Under the newly obtained certification, coating thickness on H-shaped beams can be lowered from 45 mm to25mm when JFE''s beams are used.
Broader application across steel structures
By applying the fire-resistant coating reduction method to both H-shaped steel beams and steel pipe columns,JFE expects further improvements in labor efficiency and additional construction cost reductions across a broadrange of building projects.
