Product Overview

Industrial bird cone screens, also referred to as bird guards or stack caps are installed on exhaust stacks to prevent birds from nesting or entering while allowing unrestricted exhaust flow. These components are often required to support compliance with migratory bird protection regulations and to prevent costly operational disruptions.

Unlike galvanized alternatives, our bird cone screens are fabricated from 304 stainless steel, making them suitable for high-heat and corrosive environments commonly found in industrial and oilfield applications.

Bird Cone Exhaust Stack Screen
High Temp & Corrosion Resistant

Stainless Steel Bird Cone Screen

Many bird cone screens are manufactured from galvanized steel, which is typically rated for temperatures around 392°F. In high-temperature exhaust applications, galvanized coatings can degrade quickly, leading to corrosion, reduced service life, and increased maintenance.

Our stainless steel bird cone screens are engineered to withstand elevated exhaust temperatures and harsh outdoor environments, delivering superior durability, reliability, and long-term performance.

We stock all common sizes of stainless steel bird cone screens and can design custom screens to meet specific exhaust stack dimensions and operating conditions.

Stainless steel construction provides effective bird exclusion while resisting corrosion, thermal stress, and environmental exposure. These screens are well suited for continuous service in oil & gas, refining, and industrial heating applications where performance and longevity are critical.

Stainless Steel Features

  • 304 or 316 stainless steel construction

  • Excellent corrosion resistance for outdoor and industrial environments

  • Suitable for high-temperature exhaust stacks and fired equipment

  • Long service life with minimal maintenance

  • Available in standard and custom sizes

For high-temperature, corrosive, or long-life applications, stainless steel bird cone screens are the preferred solution. Our team can help evaluate your operating conditions and specifications to determine the most appropriate material and configuration for your exhaust system.

Economical

Carbon Steel (Zinc-Coated) 

For applications with lower temperature requirements or budget-sensitive projects, we also offer carbon steel bird cone screens with a zinc-coated finish.

These options provide effective bird exclusion at a more economical price point and are commonly used where exhaust temperatures and environmental exposure are less severe.

Carbon Steel (Zinc-Coated) Features:

  • Carbon steel construction with zinc coating for basic corrosion resistance
  • Suitable for lower-temperature exhaust stacks and non-critical environments
  • Cost-effective alternative to stainless steel
  • Available in standard and select custom sizes

While zinc-coated carbon steel offers an economical solution, stainless steel is recommended for high-temperature, corrosive, or long-life applications. Our team can help evaluate your operating conditions to determine the most appropriate material choice.

Applications

  • Oil & Gas Exhaust Stacks
    Designed to protect exhaust outlets from debris, wildlife, and environmental intrusion while maintaining unrestricted airflow in upstream and midstream operations.

  • Heater Treaters
    Used on heater treater exhausts to prevent foreign material entry, improve operational safety, and extend equipment service life in production environments.

  • Fired Vessels
    Ideal for fired vessels where reliable exhaust protection is required without creating excessive backpressure or impacting combustion efficiency.

  • Industrial Furnaces and Process Heaters
    Suitable for high-temperature industrial heating applications, providing durable, low-maintenance protection in demanding operating conditions.

  • Refineries and Production Facilities
    Commonly installed across refinery and production facility exhaust systems to enhance safety, reduce maintenance concerns, and support continuous, reliable operations.

Frequently Asked Questions

How do bird cone screens work?

Bird cone screens create a physical barrier over the exhaust stack opening that prevents birds from entering or nesting while maintaining proper airflow and exhaust function.

Are bird cone screens required for compliance?

Bird cone screens are often used to help facilities comply with migratory bird protection regulations. Requirements can vary by jurisdiction and application, so customers should verify specific regulatory obligations.

What sizes are available?

We manufacture bird cone screens in standard sizes from 4" to 68" diameter. Custom sizes and configurations are available upon request.

What temperatures can these screens handle?

Our stainless steel bird cone screens are suitable for high-temperature exhaust applications, commonly up to approximately 1500°F, depending on configuration and installation.

How are bird cone screens installed?

Screens are typically installed using an adjustable stainless steel band clamp. Installation is straightforward and does not require specialized tools.

Do you offer custom designs?

Yes. We routinely manufacture custom bird cone screens to accommodate non-standard diameters, unique stack configurations, or specific operational requirements.

What is the typical lead time?

Lead times vary based on size, quantity, and customization. Stock sizes are often available quickly, and custom orders are quoted with clear production timelines.

Prevent nesting, protect equipment, and support regulatory compliance with high-quality stainless steel bird cone screens.
