BARBED WIRE

Barbed wire is a useful industrial product, mainly used for fencing purposes. Barbed wire fencing prevents the unwanted entrance and intrusion of animals and persons into the fenced area. It is commonly used in Bhutan, and it is considered one of the cheapest materials for fencing.

Thangthong Iron and Steel manufacture barbed wire using hot dipped galvanized wires. The wires are braided with a system of constant torsion, with barb prongs interlaced in the wires. The zinc-plating layer for carbon steel materials offers good corrosion resistance for the finished products.

The diameter of wire used for strands and barbs are 2.5mm and 2.65mm with a minimum distance of 75mm between two barbs. The length of barb is usually 13mm with minimum of 6mm between two barbs. Our standard roll comes in weight ranging from 30-35kg, but the weight may be customizable for bulk orders.

CHAINLINK

Chainlink wire mesh is manufactured from hot dipped galvanized wire. We manufacture high quality Chainlink wire meeting international standards in terms of consistency of physical properties, uniform coating and high surface finish. Chainlink fencing requires no maintenance at all, as it is made up of galvanised wire, giving you the benefit of no- maintenance trouble-free fencing. You may enjoy a good nights sleep knowing this fencing is giving you not only value to your property but also peace of mind.

We manufacture chainlink with wire sizes ranging from 2.5mm to 4mm in diameter and mesh eye sizes of 2”x2”, 2.5”x2.5”, 3”x3” & 4”x4”. The height of the chainlink comes in range of 3 ft. to 10 ft. and the length in 10m, 15m & 20m. However, the height and length of the chainlink wire mesh can be customized as per client’s requirement for bulk orders.

GABION BOX and MESH

Flexibility is an important benefit of any gabion structure. Since the baskets are constructed from galvanized mesh wire and filled with rocks, the flexibility of a gabion structure allows it to withstand pressure without deforming, cracking or breaking as in the case of concrete and other materials. Walls can be constructed following grade along a road, tapered on top to follow changing elevation or terraced creating stunning flower gardens that can flow over the wall.

Thangtong produces gabion box of both types- double knotted and hexagonal mesh eye (double twisted).

Hot Dipped GI Double knotted Gabion usually comes in a standard roll of 16’ width x 100’ length woven from 8 swg (4mm) wire diameter with mesh eye sizes of 100x100mm, 125x125mm & 150 x150mm. However, we also produce ready-made boxes as per client’s requirement. Some of the normal sizes include 1x1x1m, 1.5x1x1m, 2x1x1m, 2.5x1x1m, 3x1x1m and so on. For boxes whose sizes range above 1.5m length, an individual diaphragm of 1x1m is required.

Currently, Thangtong only produces hand woven double twisted gabion box. But we do have plans to install a machine in the near future. The wire size used ranges from 2.5mm to 4mm diameter. The wire used in mesh wire comes in 2.7mm/3mm diameter and the wire used in selvedge comes in 3.4mm/4mm diameter with lacing wire of 2.2mm/2.5mm respectively. The opening of the mesh comes in 100x120mm. Some of the most commonly used dimensions are 1x1x1m, 1.5x1x1m, 2x1x1m, 2.5x1x1m, 3x1x1m and so on.

FABRICATION ACTIVITIES

Another major part of our business is the fabrication activities. We fabricate angle post, flat straps, steel gates, window grills, steel railings, and such other customizable fabrication jobs.

Our advantage in fabrication is that most of the shearing, punching and notching jobs are carried out with the help of our Hydraulic Ironworker which can produce a perfect finish with precise measurements. Our multi-functional ironworker can cut and punch all kinds of materials such as plate, square bar, angle, round bar, and channel within few seconds thus saving time and energy.

Some of the commonly used angle sizes are:

1) 75x75x6mm 2) 65x65x6mm 3) 50x50x6mm 4) 50x50x5mm 5) 40x40x6mm

Some of the commonly used flat strap sizes are:

1) 65x6mm 2) 50x6mm 3) 40x6mm

Commonly used hollow structures (MS Pipe):

1) 100mm dia 2) 75mm dia 3) 65mm dia 4) 50mm dia 5)40mm dia

6)30mm dia

NAILS and U-NAILS

U-NAILS: We produce U-nails from 10 SWG (3.15mm) & 8 SWG (4mm) Hot Dipped galvanized wire for clipping and fixing barbed wire/chainlink to a fencing post (mild steel or wood post). U-nail produced by Thangtong comes in two types- machine made and hand made. Machine made u-nail is produced using only 10 SWG diameter wire and comes in length of 50mm. They usually have sharp points/edges especially for fixing to wooden post. Hand-made U-nails are produced using both 10 SWG & 8 SWG diameter wire and comes in length of 50mm to 70mm. These are usually made for fixing chainlink and barbed wire to angle post where the length of the u-nail is more than 50mm.

NAILS: We produce nails from high quality Hard Black wire that has the advantage of strength, resistance, rust and eliminates the most common problem of bend resulting in high value and minimal wastage. Thangtong produces nails from H.B wire with diameter ranging from 2.5mm to 5.4mm to give a finished product of 1” to 6” length.
