Solid wooden frame

Our frames are 100% seasoned and chemically treated.

Frames are the strongest part of a door, which is usually clamped with the brick wall with six or seven clamps, if the frame is wider than 4", 3 clamps for each side and one for the top. Thickness and width of the frame is usually 2.25" x 5.75". It has three parts. Two side parts are usually in the same length of seven feet. Top part of the frame is flexible in length, Minimum is 2.5' and maximum goes up to 10'. 3 parts are clamped together with a dovetail joint, top right and top left. Before we make the delivery, we usually stamp four braces to the frame to stabilize two angles at 90 degrees, top, middle and the bottom of the is stamped at the same width. Entrance part of the frame is usually decorated with the design bit, in the inner part of the frame which makes the frame look decorated and safer, in case someone bumps their head into it. 45 degree joints at the top right, and the to left with dovetail fitting stamp with few nails and glue make the frame very strong and sharp looking.
Exit part of the frame where the shutter usually installed has a grove in it. All the way around from left bottom to the right bottom, 0.5" x 1.5". This grove has one purpose mainly. When the door is shut locked, no burglar can enter the premises without breaking the door. One side of the frame holds the shutter with four to five hinges. Sometimes even six, depending on the size and the weight of the door. Other side of the shutter usually has a door lock or a hatch bolt from the inside of the premises.
Two types of frames are usually made, depending on the thickness and width. One type is 2.25" x 11.75",and the other is 2.25"x 11.75", is usually used for decorative entrance door, and 5.75' can be used for both (entrance and internal doors). These frames are mainly made by using - Mahogani, Barma Teak, Chittagong Shilkorai, Teak Chamble, Chittagong Teak and Loha Kath (iron wood).

About timbers for frame

Jessore Mahogany

As we know, Mahogani from Jessore is much better than any other Mahogani in the country. Basically, Mahogany timber from other districts has irregular fiber which looks indecent, color usually get faded, the difference between pal and matured part of the timber has distinct different colors and it take longer time to get the maturity. Trees planted without proper planning usually bottom part of the tree get lot wider than the top part, where the production capacity usually get less.

Mahogani in Jessore is harvested and maintained scientifically because of the quality usually get better. Since the farmers harvest them properly and take a good care of them, so they come up with a very good profit.

When the Jessore Mahogani gets matured, there is not much different between pal and matured part and also termite don’t attach them. Similar to Gamari timber there is no color different between pal and matured part, so is the mahogany of Jessore, there is no color different between pal and matured part. Since they are planted scientifically and in a well-maintained distance, so they grow taller, the width difference in a sign fact length is usually very low. So, the production is high, but the only problem is that comparatively its very expensive, but not for long run.

Chittagong Shill Karai

Chittagong Shill karai only grows in Chittagong, color may get little darker or lighter due to the geographical location of Chittagong, but they sustain the same high quality. If it grows in any other district besides Chittagong is called Kali-Karai. Quality is lot inferior, it bends, twist and fiber is not so descent.

Chittagong Shill-Karai got to be free of pal, pal will not only be attached by termite, also will be peeled of after very short time. Other problems with Shill-Karai is, you cannot make any door out of it, because it is so heavy and color is so dark.

And the color is so dark, it doesn’t go with any other timber but Burma teak. When we white polish Shill-Karai, color gets very similar to Burma teak.

It must be properly seasoned and moisture content got to be below 14%.

For frame, Shill-Karai is the best for its strength and durability.

Teak Chambul

Now these days, we import Teak Chambul from Burma. We use to collect teak chambul from Chittagong and the quality was much superior. Quality of Burma teak chambul is good for frame but not for doors.

The price we pay for Burma teak chambul is too much compare its quality, even if the moisture content is below 14% still it is difficult to control it from bending, shrinking or expanding, that’s why we don’t advice our clients to make any door out of teak chambul from Burma.

Chittagong Shegun

Chittagong Shegun grows in Chittagong, quality and fiber is very good, its pal is harmless if properly seasoned below 14% moisture content. For some obvious reason, we don’t harvest the big shegun trees, only the small and the medium size, that’s why we don’t get high quality shegun from Chittagong. We collect Chittagong teak with 2-3% pal, but from other places we collect shegun from 20-30% pal.

Chittagong Shegun pals don’t be attacked by termites, but since the pals are lighter in color, they expose after we polish them. If clients are financially solvent, we usually advise them to purchase Burma teak for much higher quality and outlook.

Burma Teak

Burma Teak grows in Burma, and we import them. There are several grades of Burma teak, like A, B, C, D. A grade Burma teak usually don’t come to our country because of their high demand in rich countries. B grade timber looks nice but little bit darker in color. Burma Teak is the best timber available for door, frame and furniture. Those who earns good money and want to buy good quality door and frame wise to invest in Burma teak. There is no other compare to this timber.

For Frame:

Before we install the frame we must apply primer and polish and the bitumen at the back part of the frame to make it waterproof. After we install the frame with the wall we have to apply water to the concrete for curing. During the application of water for curing, water will not penetrate to the seasoned timber to damage or discolor it.

Dovetail joint for frame:

Here are two pieces of frame sample. Left one for the top, right one for the vertical. We usually make this dovetail joint (some people call it finger joint) manually. We have developed couple of machines to cut this dovetail joint which is more precise than doing it manually.

We need two other machines to do the other job like - bit cutting machine to cut the bit with, other one is rabbet cutting machine which cut the rabbet in the single pass. These machines are very accurate and fast. We've been cutting rabbet and bit for a single frame within a minute.
