Technical visit to Fire-Rated Door Factory at Shenzhen

By Ir LAM Chi Sing

 

A technical visit to a Fire-Rated Door factory at Shenzhen was organized by the Materials Division on 7 April 2018. The factory - Sherex Fire-Proof Materials was established in 1996, manufacturing and suppling fire rated glazed metal and wooden doors. We watched a video showing the fire rated door test in the furnace at 60, 120, 180 or 240 minutes performed in their laboratory. It complies with international standards such as BSEN1634-1:2008, BSEN1634-3:2004 and BS476:Part22:1987. Our members then visited their workshops. It is a labour intensive manufacturing process, with PPE clad skilled workers carrying out assembly of metal door frames and panels using welding, grinding, measuring, cutting, fabrication and surface finish techniques.

 

Calcium board is the main core, placed between two steel cladding surfaces which acts as insulation and fire retardant for the fire rated doors. Fire rated resistance ironmongery was also installed in its final position. We then went to see the wooden fire rated doors which had been seasoned prior to use. Perlite cores are placed between two timber plywood/laminated decorative sheets; this material can resist a minimum of 120 minutes fire exposure. One of impressive technique was the use of a needle cutter to cut the veneer /laminated board to expose the glazed panel within the wooden door itself. This was a high precision operation and managed to cut the board without damage to the glazed panel installed within door.

 

The participants then visited the second floor to understand the spray painting operation.  There were four separate rooms for carrying out spray painting. The rooms were equipped with a water curtain and ventilation system to dilute the chemical paint which were sent down special ducts into environmental water receptor tanks for filtration before treatment and final discharge into public sewers.

 

The workshop had a high standard of housekeeping, with sawdust extracted by an artificial ventilation system at each of the work stations. All sawdust was collected, bagged and then sent off to an environmentally friendly waste disposal system.

 

Special arrangement was made by Sherex in that two steel fire rated doors specimens of different sizes were tested for 120 minutes in the furnace by an independent laboratory. Our members had chanced to observe on-the-spot fire testing of steel metal doors. 

 

Measurement were taken at 10 minutes intervals in order to observe any damage or distortion of the door panel during the test. The furnace temperature was gradually increased to 931.4 °C within the 120 minute test, with the average surface temperature reaching 140°C and maximum surface temperature reaching 246 °C.

 

The visit was very informative, with members not only now understanding the work process of fire rated door manufacturing but also look the whole process of the fire test.
