Product Overview

Paint backed keel is a metal support frame used for Modular Ceiling Systems, typically made of galvanized steel strip through roll forming, punching, connector processing, and surface paint treatment. The complete system mainly includes main keel, cross brace keel, corner keel, Suspension Wire and related installation accessories, which can be used in conjunction with ceiling panels such as mineral wool sound-absorbing board, gypsum ceiling, PVC veneer board, calcium silicate board, etc. that match the size.

The main function of the paint backed keel is to support the ceiling, maintain its flatness, and form a neat modular grid. ASTM C635 is applicable to metal Ceiling Suspension Systems that support sound-absorbing panels and embedded ceilings, and is classified into structural grades based on the ability of the main keel to withstand uniformly distributed loads.

System Composition

The main keel is the main load-bearing component of the entire ceiling system.

Horizontal bracing keel, connected to the main keel, used to form a Suspended Ceiling Grid.

Short horizontal bracing keel is usually used to form small-sized ceiling modules such as 600 × 600mm.

Corner keel, installed around the wall to support the edge of the ceiling.

Hanging wire, used to connect the main keel to the top structure of the building.

Suspension rods are suitable for ceiling projects that require high load-bearing capacity and stability.

Ceiling keel accessories, including connectors, fixings, hangers, and reinforcement accessories.

Product Features

1. Galvanized steel substrate: Paint backed keel usually uses galvanized steel as the substrate, which has good formability, structural strength, and basic anti-corrosion ability.

2. Painted surface: The visible surface of the keel has been treated with baked paint, resulting in a smooth surface and uniform color, suitable for open frame modular ceilings.

3. T-shaped structure: The product adopts a T-shaped cross-sectional design, which can stably support the ceiling panels and make the ceiling arrangement more neat.

4. Plug in connection: The main keel and cross bracing keel usually adopt a plug-in structure, which facilitates the quick assembly of the ceiling grid.

5. Lightweight: The metal keel structure is relatively lightweight, making it convenient for transportation, handling, cutting, and on-site installation.

6. Rich color options: Common colors include white, black, gold, and silver, and other colors can also be customized according to project requirements.

7. Diverse surface forms: flat painted keel, groove painted keel, black painted keel, and other decorative surfaces can be provided.

8. Wide supporting range: It can be used in conjunction with Mineral wool board, gypsum board, PVC veneer board, calcium silicate board, and other ceiling panels that match the specifications.

Product Advantages

High installation efficiency:  Paint-baked keel keel and cross brace keel adopt a modular plug-in structure, which is conducive to improving construction speed.

Good flatness of the ceiling: Accurate dimensions and stable straightness of the keel help maintain the flatness of the entire ceiling system.

Surface Aesthetics: The painted surface can be directly used as the exposed decorative part of the ceiling without the need for additional surface treatment.

Easy maintenance: Modular ceiling panels can usually be disassembled separately, making it convenient to inspect and repair the wires, pipes, lighting fixtures, and ventilation equipment inside the ceiling.

Wide applicability: can be applied to commercial buildings, public buildings, office spaces, educational institutions, and medical facilities.

Convenient transportation: The painted keel belongs to linear metal profiles, which are convenient for bundling, cardboard packaging, and container loading.

Flexible specifications: length, thickness, surface width, color, groove type, and packaging method can be adjusted according to actual order requirements.

Production process

The common production processes for Paint backed keels include:

Firstly, choose galvanized steel strip based on the thickness, strength, and anti-corrosion requirements of the product.

Then, inspect the surface, thickness, width, and galvanizing condition manufacturer Paint-baked keel of the steel strip.

Galvanized steel strip enters the roll forming equipment and is gradually processed into a T-shaped structure through multiple forming rollers.

Complete punching, connecting groove, and positioning hole processing according to product specifications.

The connection structure required for installing or processing the main keel and cross brace keel.

Paint, film, or perform other decorative treatments on the visible surface of the product.

Cut according to standard length and check the straightness of the product.

After completion, check the size, thickness, surface, interface, and plug performance.

Qualified products are classified and packaged according to model and length, and finally enter the finished product warehouse to wait for container loading and shipment.

Application Scenarios

Paint baked keel can be applied to office building ceilings to create a neat and easy to maintain modular ceiling system. It is suitable for educational buildings such as schools, universities, training centers, libraries, hospitals, clinics, waiting areas, corridors, and medical office areas, hotel rooms, hotel corridors, restaurants, conference rooms, and reception areas, shopping centers, commercial centers, supermarkets, and brand retail spaces, transportation buildings such as airports, train stations, bus stations, exhibition centers, conference centers, and public activity venues, banks, government office buildings, and public service halls, factory offices, production auxiliary areas, and ordinary indoor workshops, residential building corridors, public areas, and equipment maintenance areas; Ordinary Paint baked keel is mainly suitable for indoor dry or generally humid environments, coastal, high humidity, outdoor, swimming pools, or places with corrosive gases. A dedicated ceiling system with corresponding anti-corrosion levels should be selected.

Precautions for use

The load-bearing capacity of a paint backed keel depends on the thickness of the steel, cross-sectional structure, spacing between main keels, spacing between suspension points, and connection strength.

Ordinary ceiling joists should not be directly used to support large lighting fixtures, air ducts, and heavy equipment.

When cutting the keel, tools suitable for metal profiles should be used to avoid severe deformation of the section.

If interface damage, product deformation or obvious rust is found during installation, it should be replaced in a timely manner.

Main keels and cross bracing keels of different models and interface structures should not be mixed and used arbitrarily.

In high humidity and coastal environments, it is important to focus on inspecting the galvanized layer, anti-corrosion grade, and surface treatment of the product.

Projects with seismic requirements require ceiling reinforcement and seismic design according to local standards.

Outdoor ceilings cannot directly use ordinary indoor paint backed keels, and a specially designed and validated outdoor ceiling system should be selected.
