have established our first manufacturing plant in Dongguan
in 1988 and set up another subsidiary factory in Pengyue in
2000. The total area of the plants is about 28,000m2. We specialize
in manufacturing high quality Lightweight Expanded Clay Aggregate
(LECA) which is the crucial component of lightweight concrete.
We can produce the best lightweight precast concrete panel
which possesses the property of 2 hours fire resistance and
passes the Impact Test in accordance to BS5234-1990. In addition,
we can assemble a very safe and rigid house less than 6 hours.
Moreover, our high strength LECA lightweight concrete possesses
60Mpa and is lighter than normal concrete about 30%. If the
strength requires only 20MPa, almost 50% lighter than normal
concrete can be achieved.
LECA is an excellent fire resistant material as a result of
undergoing 1500oC manufacture process. Therefore it is a very
good component of fire resistant brick. To enhance the versatility,
a sandwich type fire resistant block developed in which a
layer of gypsum plaster will be applied on the surface of
the brick. After assembling the block wall, no extra cement
sand plaster is required prior to carry out painting work.
Hence, it will simplify the working procedure resulting in
reducing the construction cost.
We also provide custom made services. For instance, our client
requires some tiny aggregate, which is not available in the
market, for spraying work. Thus, we modify our existing production
line to manufacture these aggregates to meet the client¡¦s
specification. With our technology and innovation, our client
awarded the contract of spraying work for Hong Kong Disneyland
Our aim is to manufacture all size of LECA which is suitable
for producing all related product. LECA is an environmental
friendly product and is manufactured in accordance to BS3797-1990.
