RAINBOW Industrial Steel Chimney

RAINBOW is a professional industrial steel chimney manufacturer providing engineered steel stacks for safe flue gas discharge in power plants, boiler rooms, chemical facilities, cement plants, biomass and waste-to-energy projects. From concept design to fabrication, installation support, and maintenance, we deliver one-stop industrial chimney solutions built for high temperature, corrosion resistance, wind load stability, and long service life. 


Our industrial steel chimney range includes self-supporting steel chimneys, cluster chimneys, tower-type chimneys, and landscaped (architectural) steel chimneys. Every system is custom-designed to your process data, site conditions, and applicable standards, helping you achieve reliable draft performance and compliance-ready emissions release.


Types of Industrial Steel Chimneys

Self-Supporting Steel Chimney
Cluster Steel Chimney
Tower Type Steel Chimney
Landscaped Steel Chimney
Self-Supporting Steel Chimney

Self-Supporting Steel Chimney


Self-supporting (freestanding) industrial steel chimneys are widely used for boilers, generators, and process exhaust where a compact footprint and high structural reliability are required.

RAINBOW designs self-supporting steel stacks with a focus on strength, vibration control, corrosion protection, and safe maintenance access (platforms, ladders, manholes, and aviation warning systems as required). We have delivered large-scale projects, including a 135-meter sleeve self-supporting steel chimney. Contact us for preliminary sizing and a project-specific quotation.

Cluster Steel Chimney

Cluster Steel Chimney


RAINBOW cluster industrial steel chimneys integrate multiple flues into one compact structure—ideal for power and energy projects with limited space or multiple emission sources.

Benefits include space-saving layout, modular installation, corrosion resistance, optimized maintenance planning, and recyclable steel structure.

Each cluster steel stack is custom engineered to match your duct arrangement, thermal expansion requirements, and applicable local standards.

Tower Type Steel Chimney

Tower Type Steel Chimney


RAINBOW tower-type industrial steel chimneys use an external tower structure to support the flue, enabling very tall stacks and flexible layout solutions. The inner flue can be designed for high-temperature exhaust with appropriate insulation and corrosion protection.

This configuration is often selected when projects require large height, strong wind resistance, and convenient maintenance.

Landscaped Steel Chimney

Landscaped Steel Chimney


RAINBOW landscaped industrial steel chimneys combine emission functionality with architectural appearance—helping industrial plants meet city aesthetics, industrial park image requirements, and landmark design goals. We integrate structural safety, corrosion protection, access safety and facade/lighting concepts into one coordinated design.

If your project is located in an urban zone or has strict appearance requirements, contact our team for a customized landscaped chimney concept.

Industrial Steel Chimney FAQs

What are the benefits of using a steel chimney?

Steel chimneys offer several advantages, including durability, resistance to high temperatures, and corrosion protection. They are also customizable in terms of structure and shape, making them suitable for various industrial and residential chimney applications.

How do I choose between a self-supporting, cluster and tower-type steel chimney?

Choosing types of steel chimney involves considering factors such as geographical location, climate, working conditions, smoke characteristics, and environmental parameters.


A self-supporting chimney is often suitable where an independent structure and compact footprint are preferred. Cluster systems are useful when several flues need to be integrated, while tower chimneys provide additional structural flexibility for taller or multi-flue projects.


The final selection should be based on the actual plant layout and engineering conditions. Consulting with experts like RAINBOW Chimney can help you select the most suitable industrial steel chimney design for your specific needs.


Can steel chimneys be customized for aesthetic purposes?

Yes, steel chimneys can be designed to blend seamlessly with the landscape and architectural elements of a building. RAINBOW Chimney offers landscape chimney options to ensure that the chimney not only functions well but also enhances the visual appeal of the site.

How does RAINBOW Chimney ensure the quality of its steel chimneys?

RAINBOW Chimney integrates research and development, production, and service to ensure the highest quality standards. With decades of experience and advanced technology, we provide reliable and efficient steel chimney solutions tailored to meet specific project requirements.

How do you address corrosion in industrial steel chimneys?

Corrosion control is based on gas composition and condensation risk. Chimney solutions may include proper insulation design, suitable material selection (carbon steel + coating or stainless steel), drainage considerations, and maintenance access for inspection.

What standards can RAINBOW follow for industrial steel chimneys?

We design and manufacture according to project requirements and can support international compliance needs (such as CE/UL-related requirements where applicable), along with customer-specified codes and local regulations.


See the RAINBOW Industrial Steel Chimney PDF for additional information on our standards, qualifications and engineering capabilities.

What data is needed to design an industrial steel chimney?

Typical inputs include flue gas temperature (min/normal/max), flow rate, gas composition, dust content, allowable back pressure, required height, location (wind/seismic), and interface details (inlet/outlet, expansion joints, supports).

Can an existing industrial chimney be replaced or upgraded?

Replacement or upgrading should begin with an assessment of the existing exhaust conditions and available supporting structure. Based on that information, a new steel chimney or flue configuration can be developed to match the revised operating requirements and site limitations.


Contact RAINBOW with your existing drawings or project specifications for an initial technical review.


What information is needed to design an industrial steel chimney?

The engineering team normally starts with the required chimney height, flue gas operating data and project location. Existing duct arrangements and project specifications can then be reviewed to determine the appropriate structure, material system and connection details.
