Angle Steel Tower
Angle Steel Tower, also known as angle iron tower, serves as a structural framework primarily supporting telecommunications, линии электропередачи, and broadcasting systems. These towers are constructed using interconnected steel angles or angle irons that form a lattice framework, creating a stable structure. They can be made from ordinary carbon steel, нержавеющая сталь, or galvanized angle steel to meet different environmental requirements. The towers distribute load evenly throughout their structure, making them ideal for applications requiring height and stability.
The Angle Steel Tower plays a vital role in numerous engineering fields due to its excellent mechanical properties. They are commonly used for hanging communication antennas, installing surveillance cameras, radar devices, or fire lookout purposes. The height typically ranges from 10 к 90 метры, with most installations serving mobile carriers like China Mobile, China Unicom, and China Telecom. They feature round steel or angle steel as tower material, connected by outer flange or iron clad angle steel with tensioned bolts.

Часто задаваемые вопросы (Часто задаваемые вопросы)
How do 4-leg angle steel towers compare to 3-leg pipe towers?
Four-leg angle steel towers typically require 20-25% more steel than comparable 3-leg pipe towers. This difference stems from the greater material needed for the angle design, though they offer superior stability and load distribution for transmission line applications.
What are the standard sizes of Angle Steel Towers?
Common sizes range from 25mm×25mm to 100mm×100mm with thicknesses from 3mm to 12mm. Small angles (25-40мм) work for non-load bearing applications, medium angles (50-75мм) for standard structures, and large angles (80-100мм) for heavy-duty support. As a leading manufacturer, we can customize dimensions to your exact specifications.
How are angle steel specifications expressed?
Angle steel specifications are expressed in millimeters as width×width×thickness (например, ∟30×30×3) for equilateral angles. They can also be expressed by model number (2#-20#), though contracts should specify exact dimensions to avoid confusion.
What components make up an Angle Steel Tower?
Angle Steel Towers comprise brackets, скрестить руки, tower bodies, and tower legs. All parts except standard components like bolts, flanges, clamping plates, foot pins and washers are numbered in structural drawings for precise assembly and maintenance.
How do I measure and select the right angle bar size?
Select angle bar size by understanding specifications, assessing load requirements, and measuring available space. For high-rise structures, larger angles (80mm×80mm, 10mm thick) are needed, while residential applications may use smaller angles (40mm×40mm, 5mm thick).
What are the main types of Angle Steel Towers available?
Angle Steel Towers come in several configurations including four-legged towers, three-legged triangular towers, guyed towers, and self-supporting towers. Each type serves different purposes – four-legged designs offer maximum stability, triangular towers use less material, and guyed towers work well for greater heights.
What materials are used in manufacturing Angle Steel Towers?
Most Angle Steel Towers use Q235B or Q345B steel with minimum yield strength of 345N/mm². Some manufacturers also offer towers made from structural aluminum 6061-T6 for specific applications. Material selection depends on load requirements, условия окружающей среды, and cost considerations.
What is the typical production timeline for Angle Steel Towers?
Standard Angle Steel Towers typically require 30-45 days from order to delivery. Custom designs may take longer depending on complexity. As a leading manufacturer, we can expedite production for urgent projects while maintaining quality standards throughout our ISO-certified manufacturing process.
What wind speeds can Angle Steel Towers withstand?
Our Angle Steel Towers are engineered to withstand wind speeds ranging from 30m/s to 50m/s (108-180 km/h) depending on the design. For areas with extreme weather conditions, we can custom design towers to handle wind speeds up to 300 km/h with appropriate reinforcement.
What surface treatments are available for Angle Steel Towers?
We offer hot-dip galvanization following ASTM A123 standards as the primary surface treatment, providing 30+ years of corrosion protection. Alternative finishes include polyester powder coating in various colors for aesthetic purposes or additional environmental protection in harsh conditions.
