Towers, Transmission & Distribution
Towers, Transmission & Distribution

Transmission lines carry electricity over long distances. Transmission towers are large structures that support the high-voltage transmission lines. These lines typically feed into a substation so that the electricity can be reduced to a level that can subsequently be used by our customers.

A transmission tower (also known as a power transmission tower, power tower, or electricity pylon) is a tall structure (usually a steel lattice tower) used to support an overhead power line. In electrical grids, they are used to carry high voltage transmission lines that transport bulk electric power from generating stations to electrical substations; utility poles are used to support lower-voltage sub-transmission and distribution lines that transport power from substations to electric customers.

Transmission towers have to carry the heavy transmission conductors at a sufficient safe height from the ground. In addition to that, all towers have to sustain all kinds of natural calamities. So transmission tower design is an important engineering job where civil, mechanical, and electrical engineering concepts are equally applicable.

We manufacture all the hardware and the fasteners related to the tower acessories.

Recommended products for the industry

Foundation Bolts

 A foundation bolt is a steel product in the form of a rod with a threaded part; consists of a metal rod and a special device that holds the foundation bolt inside the foundation. It is used for fastening structures in the construction of residential buildings, industrial buildings, roads, etc. 

Size Range
Diameter

1/2" to 2"

Length

6" to 48"

Heavy Hex Structural Bolt

Heavy hex structural bolts are designed for steel-to-steel connections and include ASTM A325 and A490 specifications, which covers bolts from 1/2” up to 1-1/2” in diameter. Since these heavy hex bolts are intended for structural connections, they have shorter thread lengths than standard hex bolts.

Heavy Hex Bolts are designed for use in a variety of high temperature, high strength industrial applications, such as with steel fabrication and general construction. They feature a thicker head than standard or regular hex bolts, and offer a greater bearing surface that distributes the clamping load over a wider area.

Hex Head Bolt

As the name implies, these bolts feature a hexagonal head or a hex head, that is suitable for tightening with a wrench or socket. A hex bolt may be fully threaded or may feature an unthreaded shoulder. Hex bolts are often used to fasten wood to wood, metal to wood, or metal to metal

HSFG Bolt Assembly

High strength bolts or structural bolts are made to be used with heavy hex nuts to connect structural members. To be considered a structural connection, it has to conform to specific ASTM standards; specifically, ASTM A563 or ASTM A194.

Structural bolts are also categorized by grades. The grading system takes into consideration the bolt’s material, its size range, its proof load, the minimum yield strength, and the minimum tensile strength.

Square Head Bolt

Square Head Bolts are similar to Hex Cap screws but have a 4-sided square head instead of a 6-sided hexagonal head.They are commonly referred to as both bolts and screws and are designed to be driven with a wrench. Square Head Bolts are partially threaded with a shoulder beneath the head.

Spring Lock Washer

Unlike flat washers, which are placed on both the bolt and nut side, spring washers only go on the nut side of the fastener to establish a bond. A spring washer offers axial flexibility that's intended to prevent loosening of the fastener with which it's paired.
