Using Q355B high-strength steel and ASTM A123 standard hot-dip galvanizing process, the Steel Observation Tower provides an anti-corrosion life of more than 50 years and has been tested to resist 160 km/h hurricane, providing all-weather stable support for forest fire prevention and border monitoring and one-stop bulk supply.
Body material:
Q355B steel
Design wind resistance:
160 km/h
Anti-corrosion life:
≥ 50 years
It adopts hot-dip galvanizing treatment with full coverage inside and outside. The thickness of zinc layer is strictly controlled above 85μm, which effectively isolates oxidation. In coastal high salt fog or humid forest environment, the tower body is guaranteed not to rust for 50 years and does not need frequent maintenance and recoating.
Low alloy high strength structural steel with yield strength ≥ 355MPa is selected. Compared with ordinary A36/Q235 steel, the structural bearing capacity is increased by 30%. Under the same design height (e.g. 30 m), the tower body weight is reduced by 15%, thus reducing the foundation cost.
Through finite element analysis optimization of the triangular or four-corner truss structure, the drag coefficient is reduced to less than 0.6. Even under the extreme wind speed of 160 km/h, the swing amplitude of the tower top is controlled within 1/400 of the height to ensure that the picture of the monitoring equipment does not shake.
The whole tower is prefabricated in the factory, and is connected on site by 10.9-grade high-strength bolts, and the anti-slip coefficient of the friction connection surface is greater than 0.45. The risk of weld flaw detection caused by on-site welding is avoided, and the installation efficiency is 60% higher than that of the traditional welding tower.
Equipped with a straight ladder with a safety guard cage or a 45-degree inclined ladder, the step adopts a 3mm thick patterned steel plate anti-skid design, and is matched with a 1.1-meter-high industrial guardrail, which fully meets OSHA and international safety standards for aerial work to ensure the safety of patrol personnel.
Steel Observation Tower adopts standardized segmented design (3-6 meters per segment), and the height can be flexibly adjusted (10m-50m) according to site requirements. The standard equipment installation interface is reserved on the top platform, which is compatible with radar, PTZ camera and communication antenna.

Structural rigidity and safety upgrade
In terms of structural safety, this product refuses to follow the common “angle steel simple connection” method on the market, but innovatively introduces the gusset strengthening technology. This 1 depth optimization makes the node connection stiffness of the tower body 40% higher than that of traditional products. This high-strength rigid connection effectively solves the problem of bolt loosening that is easy to occur in the watchtower under long-term wind load and vibration environment, fundamentally eliminates the hidden danger of structural safety, and ensures that the tower body is still stable and reliable in bad weather.
Extreme anti-corrosion and surface process
In the surface treatment, we abandon the low-end products to save costs and simplify the process, strictly implement the “pickling-washing-assisted plating-drying-hot dip” of the whole process of galvanizing process. This 1 rigorous closed-loop process completely solves the common problem of “leakage plating” or “zinc peeling” in the industry. We promise that every inch of steel surface can form a dense alloy layer, to ensure that the tower body to obtain a complete cathodic protection, even in humid or highly corrosive environment, can maintain a long-term bright, significantly extend the service life of the equipment.
In view of the high humidity environment of forest and seaside, the problem that ordinary antirust paint coating can only maintain 3-5 years and begin to peel off and rust is solved, and the zinc-iron alloy layer combined with metallurgy provides long-term physical and electrochemical dual protection.
In view of the extremely high requirements for stability of security monitoring, the problem that the remote camera cannot focus due to the shaking of the traditional tower body with too large slenderness ratio under gusts of wind is solved, and the tower body stiffness is locked by increasing the tower base span and optimizing the angle of the truss diagonal rod.
In view of the construction pain point that large cranes cannot enter in mountainous and forest areas, the problem that the traditional heavy tower body is difficult to install is solved. The component design of “breaking up into parts” is adopted, and the weight of a single piece is controlled within the lifting range of manpower or light holding rods.
It is suitable for fire prevention warning systems that need to cover thousands of hectares of forest. The Steel Observation Tower can be equipped with a pyrotechnic identification thermal imaging camera, providing an all-weather high-point monitoring perspective for early detection of fires.
It is suitable for operation and maintenance monitoring of large wind farms, photovoltaic power stations and transmission hubs. The stable steel structure tower body can carry high-precision inspection equipment and meteorological sensors, carry out remote troubleshooting, fire warning and security alert on the vast energy facilities, and greatly reduce the cost of manual inspection.
Applicable to the construction of high-altitude viewing platform. The product is not only structurally safe, but also has a strong industrial aesthetic appearance. It can be equipped with revolving stairs and glass plank roads to carry a large number of tourists to climb and overlook the scenic spot and enhance its attractiveness.
Suitable for a wide range of logistics scheduling monitoring. In container yards or chemical plant areas, watchtowers above 30 meters can eliminate blind spots in the line of sight, assist managers in dispatching vehicles and machinery, and improve operational efficiency.
01
Before pouring the concrete foundation, be sure to use the positioning template to fix the anchor bolts, and ensure that the center distance error of adjacent anchor bolts is controlled within ± 2mm, so as to ensure the smooth installation of the first section of the tower body.
02
Following the principle of “bottom-up”, it is recommended to assemble and form the standard section every 3-6 meters on the ground, check the diagonal error <3mm, and then hoist and dock as a whole to reduce the working time at high altitude.
03
The connecting bolts must be tightened with a torque wrench. The initial tightening reaches 50% of the standard torque and the final tightening reaches 100. The recommended final tightening torque of Q355 steel structure M20 bolt is usually between 400-500 N · m (refer to the specific design drawing).
04
After each section of tower is installed, theodolite must be used to detect the verticality of the tower from two mutually perpendicular directions. The deviation of the overall verticality shall not exceed 1/1500 of the tower height. If it exceeds the standard, fine adjustment shall be made through the gasket.
The standard design can withstand wind speeds from 120 km/h to 160 km/h (equivalent to a 12-14 typhoon). For hurricane-prone areas, we can customize a reinforced version with wind resistance of more than 180 km/h by increasing the cross section of the main material and reducing the slenderness ratio of the tower body.
The tower body is packaged and delivered in full parts (Knocked-down). All parts are tied into a compact steel belt bundle, which greatly saves transportation volume. A 1333.32cm high tank (40HQ) can usually carry 2-3 standard observation towers 30 meters high, which is very suitable for international shipping.
For a skilled 5-person installation team, when the foundation concrete has been completely cured, it usually takes 3-5 days to complete the assembly and hoisting of the main structure. We can provide detailed CAD installation drawings and video guidance.
We can provide basic reaction force data (upper pull force, lower pressure, horizontal shear force). Due to the different soil geological conditions (such as sand, rock, frozen soil), it is recommended that the buyer provide these data to the local civil engineer for specific concrete foundation design.
Although the hardness of the hot dip galvanized layer is high, if slight mechanical damage occurs, we will provide cold Galvanizing paint with high zinc content with the goods. After on-site coating, its anti-corrosion performance can be equivalent to the original hot-dip galvanized layer.
Yes. Our Steel Observation Tower is a multi-purpose tower and has been designed with additional load allowance. You can easily install a WiFi base station, microwave antenna or lightning rod on the tower or top platform.
