Self-Support Towers
_edited.jpg)
Self-Support Towers are engineered for PCS/Cellular and point-to-point communication applications, designed in accordance with CSA-S37 or EIA/TIA-222 standards. Additional specifications can be accommodated upon request. All tower components are constructed from hot-dip galvanized steel for optimal environmental protection, meeting ASTM and CSA standards. Welding adheres to both CWB and AWS specifications.
Elements
SSTL
A Self-Supporting Tower Line (SSTL) is a type of telecommunications structure designed to stand independently without the need for external support, such as guy wires or anchors. These towers have a wide base and tapered design, which provides stability and strength, allowing them to support various types of communication equipment, including antennas, satellite dishes, and other broadcasting instruments.
​
SSTLs are often constructed from sections of steel and can reach significant heights while maintaining structural integrity, even under harsh environmental conditions. Due to their ability to be installed in relatively small spaces and their strong wind resistance, self-supporting towers are ideal for cellular, radio, television, and point-to-point communication, particularly in urban or remote areas where space or terrain limits the use of guyed towers.
UXL
An Ultra Extra Light (UXL) tower design is a lightweight, efficient communication tower structure ideal for applications in cellular, PCS, point-to-point communications, and wireless internet. UXL towers are designed to support smaller, lighter equipment, making them practical for remote or restricted-access areas where transport and installation need to be streamlined.
​
The structural components include tower legs made of 60° angles, with braces differing by standard: the CSA-S37 version uses 90° steel channel braces, while the EIA-222 version utilizes tubular steel braces. All connections are securely bolted, and every steel component is hot-dip galvanized (H.D. Galvanized) after fabrication for maximum durability against environmental exposure.
​
These towers are available in heights ranging from a minimum of 6 meters (20 feet) to a maximum of 36 meters (120 feet), making them versatile for various site requirements and wind load conditions.
UR
In communication tower terminology, UR, commonly stands for Ultra Radio. This designation refers to a type or specification of tower or equipment designed specifically for high-frequency radio transmission. UR towers are typically engineered to handle advanced radio equipment, often used in applications that require reliable, high-quality transmission for radio, cellular, or broadband communication systems. The "Ultra" component indicates enhanced capabilities or specifications suitable for demanding or high-performance environments.​
​
The UR tower is a narrow-base, light-duty self-supporting structure designed for wireless networks and point-to-point communication. It can be equipped with climbing facilities such as step-bolts, climbing ladders, safety rails, and safety hoops for safe access.
​
The standard height of the UR tower is 36 meters (120 feet), with optional extended heights up to 48 meters (157 feet) available upon request for low-wind areas.
