The company
The largest single-line cement sheet manufacturer in the world
Anwar Cement Sheet Ltd. (ACSL) is the fibre cement roofing concern of Anwar Group of Industries, one of Bangladesh’s oldest business houses.
ACSL was incorporated in 2013 and runs a single production line built on German technology, described by the company as the largest of its kind in the world. Around 1,250 people work across manufacturing, quality control, distribution and dealer support.
The plant manufactures to ISO-393:1964 and BDS 1046:1983 and is approved by the Bangladesh Standards and Testing Institution (BSTI). Every sheet is a 6-layered fibre cement product, 4 mm thick, in lengths from 2 to 10 RFT, in natural grey or factory-coloured red, blue and green.
ACSL sits inside the group's Building Materials Division alongside Anwar Cement, Duraroof, Anwar Galvanizing, Anwar Ispat and A1 Polymer, so the roof, the structure beneath it and the fixings can all come from one trusted source.
Weather readiness
How the roof handles each season
The roof has become part of a family's comfort plan and a farm's productivity plan. Here is how a fibre cement roof behaves in each season.
Weather readiness
Protection through every season
Heat waveLower heat transfer keeps interiors up to 12°C cooler.
Heavy rainDense sheet dampens rain noise; correct overlap manages monsoon exposure.
Cold waveThermal insulation reduces sudden indoor temperature swings.
Storm seasonProfessional fixing on the corrugation crest supports roof integrity.
Performance
Fibre cement roofing designed for everyday heat, rain and humidity.
Technology
German-technology single line for consistent sheet quality, every batch.
Installation support
Guidance on slope, overlap, fixing and accessories through the dealer network.
Warranty
10 years of guarantee, based on approved terms and correct installation.

BUET test certification
Tested by BUET, our long-term research partner
I am glad to see Anwar Group introducing DuraRoof in Bangladesh; indeed a long awaited solution to all the perils of conventional steel based roofing materials. Test results from BUET of DuraRoof were impressive to me.
DuraRoof holds the capacity to withstand very high temperatures as the test results show. In addition, its anti-rusting elements make it an appropriate roofing solution for all industrial usage. The confidence of the promoters in the products also resounded in the offering of 50 years rust-free guarantee.

Partnership
Roofing Bangladesh’s first EV manufacturer
A smart roofing partnership with Bangladesh Auto Industries Ltd., supplying roofing sheet for its factory sheds.
Anwar Group
A family conglomerate since 1834
DuraRoof is believed to be yet another revolutionary product. It is anti-corrosive, anti-rusting, fire resistant and an excellent heat insulator. It not only outlives the conventional steel roofing by up to five times, but also induces higher efficiency and productivity by improving temperature and humidity control inside the plants.
Beyond Bangladesh, DuraRoof is also exported to India and Pakistan. By 2026, DuraRoof hopes to be able to export to at least 12 different countries.

Major concerns of Anwar Group
Sustainability
A durable and sustainable roofing solution
How cement sheet roofing supports cooler factories, green building certification and the Sustainable Development Goals.
Bangladesh is at high risk for extreme heat hazards, and the risk is rising. Air conditioning run on fossil fuel creates a vicious circle: more cooling, more emissions, a warmer climate. Cement sheet roofing is a passive, long-term cooling system for factories.
- Reduce absence rates and productivity loss
- Sustainable composition
- Mitigate temperature up to 12 degrees Celsius
- Increase livestock production and reduce farm operating expense
- Reduce the physical and psychological impacts of heat stress
