Steel Structure Chimney - High - Quality, Durable & Customizable Industrial Solution
As a core component of modern industrial infrastructure, our steel structure chimney is engineered to meet the strictest industry standards. It combines high strength, corrosion resistance, and easy installation. Suitable for various industrial scenarios, it provides reliable exhaust gas discharge solutions while complying with environmental protection requirements.
Below is a detailed introduction to our product, including features, advantages, specifications, applications, and customization services.
Product Features
High-Strength Structural Design
Adopts high-strength structural steel (Q235B, Q355B, Q355E, etc.) as the main material, with truss or space lattice design to achieve light weight and high stability. The overall structure is firm and can withstand strong wind, earthquake, and other harsh natural conditions, complying with relevant national and international standards such as EN 13084 / EN 1993 - 3 - 2 and Chinese national standard 08SG213-1.
Excellent Corrosion Resistance
Surface treatment adopts hot-dip galvanizing + epoxy zinc-rich primer + polyurethane topcoat, and welds are protected with special weather-resistant electrodes and zinc-aluminum coating to avoid local corrosion. Inner cylinder can be made of stainless steel (SUS304, 316L), FRP, or titanium-steel composite plate according to flue gas characteristics, effectively resisting acid, alkali, salt fog, and high-temperature corrosion.
Modular Prefabrication
All components are prefabricated in the factory with CNC assembly line and laser processing technology, using Daheng software for lofting to ensure high precision. The modular design allows on-site hoisting and splicing, greatly reducing on-site construction time and labor costs.
Integrated Functional Design
Equipped with full-steel anti-slip inspection platform and ladder for easy daily maintenance and inspection. The outer cylinder is covered with rock wool or aluminum silicate insulation layer, with galvanized steel plate protective shell outside to achieve good thermal insulation effect, prevent wall condensation, and stabilize flue gas flow rate and temperature.
Environmentally Friendly & Recyclable
The whole steel structure can be 99% recycled after scrapping, conforming to the green manufacturing trend, and reducing environmental pollution. The streamlined design enhances thermal buoyancy, promotes high-altitude diffusion of flue gas, and reduces ground pollutant concentration.
Product Advantages
Light Weight & Low Foundation Load
Compared with concrete chimneys, the self-weight of steel structure chimney is reduced by 30%-50%, which greatly reduces the requirements for foundation bearing capacity, saves foundation construction costs, and is especially suitable for soft soil foundations and complex terrain areas.
Short Construction Period
Factory prefabrication and on-site modular assembly can shorten the construction period by more than 40% compared with traditional concrete chimneys. For example, the production and installation period of a 100-meter chimney does not exceed 3 months, helping customers put into production quickly.
Strong Adaptability
It can be flexibly designed and installed according to different application scenarios, such as industrial plants, power stations, chemical parks, offshore platforms, etc. It is suitable for seismic fortification intensity ≤9 degrees, flue gas temperature -30℃ ~ +600℃ (special materials can reach 800℃), and can adapt to high altitude, high salt fog and other harsh environments.
Low Maintenance Cost
The modular design supports local replacement of damaged components, avoiding overall demolition and reconstruction. With excellent corrosion resistance, the service life can reach 30-50 years under regular maintenance, and the maintenance frequency is low, reducing long-term use costs.
Compliance with Environmental Standards
Strictly in line with international and local environmental protection regulations, it can effectively discharge industrial waste gas, flue gas, and other pollutants, and can be integrated with SCR denitration system to meet higher environmental protection requirements, such as waste incineration plants and chemical enterprises.
One-Stop Service Guarantee
Provide one-stop service from scheme design, stress calculation, production and manufacturing, installation guidance to after-sales maintenance, with free design service and national installation support, and lifelong quality assurance to solve customers' worries comprehensively.
