Which Roof Smoke Ventilator is Better? Five Key Selection Points for Steel Structure Factory Owners
Release time：
For owners of steel structure factories, selecting the right smoke ventilating skylight is not only a crucial choice for the comfort of the workshop environment and employees’ health but also a vital guarantee for fire safety and production efficiency. Faced with a wide variety of products on the market, they may wonder how to make an informed decision and here are five tips for reference.
Tip 1: Clarify Primary Functional Needs and Differentiate Types
First, they should identify the primary purpose of installing the smoke ventilating skylight. If the main goals are daily ventilation, daylighting, and energy efficiency, natural ventilation skylights or electric daylighting smoke ventilating skylights are suitable choices. These types will effectively improve stuffy environments and reduce mechanical ventilation energy consumption. If the core objective is to comply with fire safety regulations and ensure rapid smoke and heat exhaust during a fire, focus on selecting skylights with outstanding smoke exhaust performance, such as low-profile ventilation skylights, triangular electric skylights (top-opening type), or linear electric skylights. The motors should include emergency power supply, signal feedback functions, and support integration with fire safety systems.
Tip 2: Match Factory Structure and Load Requirements
The load-bearing capacity, roof slope, and purlin spacing of the steel structure factory are the basic parameters required for selection. The base design of the factory ventilation and smoke ventilating skylight must perfectly align with your factory’s structure to ensure stable installation. Calculate the skylight’s own weight (dead load) as well as wind and snow loads (live load) in detail to ensure safety under extreme weather conditions and avoid excessive stress on the original steel structure.
Tip 3: Focus on Core Materials and Craftsmanship
The durability of the skylight depends on its materials. Profiles should be made of high-quality hot-dip galvanized steel panels, aluminum alloy panels, or stainless steel panels to ensure strength and long-term corrosion resistance. Daylighting sections typically use FRP daylighting panels or PC panels, with attention to light transmittance, UV resistance, and fire rating. Waterproofing is particularly critical; electrically operated smoke ventilating skylights with structural waterproofing technology offer long-lasting waterproofing and eliminate leakage risks in the factory.
Tip 4: Prioritize Opening/Closing Methods and Control Systems
The opening and closing method directly affects convenience and reliability. Electric control is the mainstream trend, enabling remote and centralized control or intelligent integration with fire safety systems. Although it involves higher costs, it offers high automation and rapid response. When opting for electric control, ensure the motor brand, protection rating (recommended IP54 or higher), and manual emergency opening function are confirmed.
Tip 5: Verify Fire Safety Certification and Manufacturer Services
For roof-mounted electric smoke ventilating skylights, the control box and electric push rod must obtain national fire safety product certification (such as CCCF certification), which is a mandatory requirement for approval. Additionally, it is crucial to inspect the manufacturer’s comprehensive service capabilities, namely to evaluate whether they can provide professional structural load calculations, detailed design solutions, and reliable installation guidance and after-sales service support.
In summary, when purchasing a factory smoke ventilating skylight, the buyer adhere to the above five points. Based on your needs, combine them with the actual conditions of your factory, and choose compliant, reliable, and well-matched products and service providers.
