waffle mold

Nonpermanent Blocks (Waffle):

The second product of the company is the waffle hollow slab mold. The idea of twosided waffle slabs introduced with nonpermanent molds in the first half of the 20th century and used in the United States since 1940 and due to its efficient performance in ceilings with large spans, its use rapidly increased. In Iran, many of the important buildings and infrastructure such as universities, hospitals and hotels, etc., have been built using this technology. The molds design of the Gonbad Firoozeh Company with great technical and economic benefits compared to the existing ones in the market. The ceiling mold is made of composite plastic which is very light and its glossy surface causes to use the bottom concrete view to be featured as expose. The slabs are also introduced in the 9th section of the National Building Regulations, with T-shaped “orthogonal beams”.
