MECTRON provides 2 hour fire rated Rectangular Galvanized Steel / Mild Steel ductwork tested as per BS476
Part 24:1987, both for coated and non-coated fire resistant systems complying to following applications:
✓ Ventilation & Stair Pressurisation
✓ Smoke Extraction for Kitchen Hood
✓ Basement Car park exhaust.
For coated fire resistant ductwork, duct is manufactured as per DW144/SMACNA standards. An Intumescent (fire resistant / fire retardant) coating of minimum thickness is sprayed over duct outer surface, which sustain high temperature of fire. Due to flame resistant quality of coating, the duct is able to maintain its stability and integrity for 2 hours as tested in a fire test.
Non-Coated fire resistant ductwork system is without any fire resistant / fire retardant coating. By virtue of its material, special flange design, duct stiffening & special construction, support system components, the duct is able to sustain high temperature when fire tested to BS476 Part 24. Non-coated duct maintains the stability and integrity for 2 hours
Precision dimensioning, speed and excellent raw material utilization are provided by fully automated, computer-controlled machines such as the
Auto folder which selects the required sheet gauge, levels, provides stiffening ribs, notches, folds and shears for the manufacture of folds, 'L', 'U' and fully boxed sections
Plasma Profile Cutter which produces the widest range of profile for elbows, tapers, offset, branches and other sections.
