| Standard Width | Usually 28–32 inches |
| Popular Width | Around 32 inches in many markets |
| Effective Coverage Width | Around 26–30 inches after overlap |
| Common Lengths | 6 ft, 7 ft, 8 ft, 9 ft, 10 ft, 12 ft |
| Common Thickness Range | Around 0.20 mm to 0.40 mm+ |
| Most Used Sizes | 8 ft, 10 ft, 12 ft |
| Common Uses | Homes, shops, garages, warehouses, farms, factories |
However, sizes may vary depending on brand, sheet profile, coating, and dealer availability. Always confirm the actual measurement before purchasing.
Bangladesh Dhew Tin Size Chart
Dhew tin is usually measured by length in feet. Width and thickness are also important, but most buyers first ask for the sheet length. Below is a practical size chart for Bangladesh.

| Dhew Tin Length | Common Use |
|---|---|
| 6 feet | Small kitchens, temporary sheds, small shops, verandas |
| 7 feet | Side sheds, small rural houses, poultry or light farm structures |
| 8 feet | Homes, shops, garages, small and medium tin sheds |
| 9 feet | Medium rooms, house extensions, small institutional sheds |
| 10 feet | Main house roofs, garages, market sheds, small warehouses |
| 12 feet | Large houses, warehouses, factories, agricultural and commercial sheds |
6 Feet Dhew Tin
In the Dhew Tin Er Map guide, 6 feet dhew tin is usually suitable for small structures where the roof span is limited. A 6 feet sheet is easier to carry, easy to install, and helps reduce unnecessary cutting. However, it is not ideal for large roofs because more joints may increase the risk of leakage.
8 Feet Dhew Tin
According to common Dhew Tin Er Map in Bangladesh, 8 feet dhew tin is one of the most popular choices. It is commonly used for homes, small shops, garages, verandas, and rural tin-shed houses. It offers a good balance between coverage, handling, and installation cost.
10 Feet Dhew Tin
For medium to large roof areas, 10 feet dhew tin is an important size in the Dhew Tin Er Map chart. It is suitable for main roof areas, larger rooms, garages, shops, and small warehouses. If the roof slope is longer, 10 feet sheets can reduce joints and make the installation cleaner.
12 Feet Dhew Tin
In Bangladesh, 12 feet dhew tin is another common size in Dhew Tin Er Map, especially for larger roofing projects. A 12 feet sheet is mostly used for larger roofs, factory sheds, commercial structures, agricultural storage, and warehouses. It can reduce overlap points, but it requires a stronger frame and proper fixing.
Dheu Tin Er Map - Width and Effective Coverage
Many buyers only ask about length, but width is equally important. In Bangladesh, dhew tin width is usually around 28 inches to 32 inches. In many markets, 32-inch sheets are common.
| Width Type | Meaning |
|---|---|
| Total width | Full width of the sheet from one side to another |
| Effective width | Actual coverage after overlapping with the next sheet |
For example, if a sheet has a total width of 32 inches, the effective coverage may become around 28–30 inches after overlap. This happens because one side of the sheet must sit over the next sheet to prevent rainwater leakage.
So, when calculating how many sheets you need, use the effective width, not only the total width.
How to Calculate Dhew Tin Sheet Quantity
Let’s say your roof width is 20 feet, and each sheet gives around 2.5 feet of effective coverage after overlap.
Calculation:
20 ÷ 2.5 = 8 sheets
So, you may need around 8 sheets for one row of that roof section. If the roof has two slopes, you will need to calculate both sides separately.
This is only a basic example. The final number depends on roof design, slope, overhang, cutting, wastage, and overlap.
Dhew Tin Thickness Guide
Thickness affects strength, durability, weight, and price. A thicker sheet is usually stronger and more durable, but it also costs more. For long-term roofing, thickness should never be ignored.
| Thickness | Grade Type | Suitable Use |
|---|---|---|
| 0.20 mm | Light grade | Temporary sheds, low-budget short-term work |
| 0.25 mm | Basic grade | Small rooms, verandas, light roofing |
| 0.30 mm | Standard grade | Homes, garages, shops, regular tin sheds |
| 0.35 mm | Better grade | Long-term homes, shops, medium warehouses |
| 0.40 mm+ | Heavy grade | Factories, large warehouses, commercial sheds |
Which Thickness Is Better for Homes?
For normal residential roofing in Bangladesh, 0.30 mm or 0.35 mm is often a balanced choice. It provides better durability than very thin sheets and is still manageable in terms of cost.
For factories, warehouses, and large commercial sheds, 0.40 mm or thicker may be a better option, depending on the structure and weather exposure.
Why Dhew Tin Weight Changes by Size
The weight of dhew tin depends on several factors:
| Factor | How It Affects Weight |
|---|---|
| Length | Longer sheets use more metal, so weight increases |
| Width | Wider sheets may weigh more |
| Thickness | Thicker sheets are heavier and stronger |
| Coating | Zinc or color coating can affect weight and durability |
| Material quality | Better raw material and consistent thickness improve performance |
A 12 feet sheet will usually weigh more than an 8 feet sheet if both have the same thickness and width. Similarly, a 0.35 mm sheet will weigh more than a 0.25 mm sheet of the same size.
However, more weight does not always mean better quality. You should check thickness, coating quality, wave shape, brand authenticity, and warranty.
How to Choose the Right Dhew Tin Er Map for Your Project
The best size depends on the type of structure, roof design, and budget. Here is a practical guide.
| Project Type | Recommended Size |
|---|---|
| Small veranda or kitchen | 6 ft or 7 ft |
| Small rural house | 8 ft |
| Regular home roof | 8 ft, 10 ft, or 12 ft |
| Garage | 8 ft or 10 ft |
| Shop or market shed | 8 ft, 10 ft, or 12 ft |
| Warehouse | 10 ft or 12 ft |
| Factory shed | 12 ft or custom size |
| Poultry or farm shed | 7 ft, 8 ft, 10 ft, or 12 ft |
For homes, durability is very important. So, do not select only based on low price. Consider size, thickness, coating, and installation quality together.
For factories and warehouses, large sheets can reduce joints, but the frame must be strong enough to support the sheet properly.
Things to Check Before Buying Dhew Tin
Before purchasing, check the following points carefully:
| Checklist | Why It Matters |
|---|---|
| Size | Ensures correct roof coverage |
| Thickness | Affects durability and strength |
| Weight | Helps compare quality between similar sheets |
| Coating | Protects against rust and weather damage |
| Brand mark | Helps avoid fake or low-quality products |
| Wave shape | Ensures proper fitting and water flow |
| Surface finish | Avoids rusty, damaged, or uneven sheets |
| Warranty | Adds confidence and after-sales support |
| Dealer reliability | Reduces the risk of wrong or duplicate products |
| Effective coverage | Helps calculate the correct sheet quantity |
Also, ask your mason, engineer, or contractor about proper overlap, screw placement, roof slope, and frame spacing. Even good-quality tin can leak if installation is poor.
Common Mistakes When Choosing Dhew Tin
| Mistake | Correct Understanding |
|---|---|
| Thinking all sheets have the same width | Width can vary by brand and profile |
| Choosing only by length | Width, thickness, coating, and weight also matter |
| Buying the cheapest sheet | Low-quality sheets may cost more later due to repair |
| Ignoring effective coverage | Overlap reduces actual coverage |
| Thinking thicker is always necessary | Thickness should match the structure and budget |
| Not checking brand authenticity | Fake or poor-quality sheets may not last long |
| Ignoring installation quality | Poor fixing can cause leakage even with good tin |
Final Buying Tips for Bangladesh
If you are buying dhew tin for a house, choose a size that matches your roof slope and frame. For small homes, 8 feet may be enough. For larger roofs, 10 feet or 12 feet can reduce joints and improve coverage.
If you are buying for a garage, shop, or warehouse, check both length and thickness carefully. For factories and commercial sheds, consult an experienced installer or engineer before finalizing the size.
Most importantly, do not calculate sheet quantity using total width only. Use effective coverage width after overlap.
Conclusion
Understanding Dhew Tin Er Map is essential before buying roofing sheets in Bangladesh. The most common lengths are 6 ft, 7 ft, 8 ft, 9 ft, 10 ft, and 12 ft, while 8 ft, 10 ft, and 12 ft are the most widely used for homes, shops, garages, warehouses, and commercial sheds.
Along with size, you should also check width, effective coverage, thickness, weight, coating quality, brand authenticity, and installation method. The right Dheu Tin Er Map can reduce waste, control cost, improve durability, and protect your structure for many years.
Before purchasing, talk to a reliable dealer, mason, or engineer. A correct size, proper thickness, and quality installation will help your roof stay strong, safe, and long-lasting.
