Double-point fixing system of plastic handrails: material and performance analysis
In modern buildings and home environments, two point plastic handrails(bracket) are widely used because of their advantages such as lightness, corrosion resistance, and variety of colors. As a common installation method, the double-point fixing system can provide a stable support for plastic handrails, ensuring their safety and reliability during use.
1. Material characteristics
(I) Plastic handrail materials
Plastic handrails are usually made of materials such as polyvinyl chloride (PVC), polycarbonate (PC) or polypropylene (PP). These materials have the following characteristics:
Corrosion resistance: Plastic materials have good tolerance to chemical substances such as acids and alkalis, are not easily corroded, and are suitable for use in humid or chemically complex places.
Lightness: The density of plastic materials is low, making the overall weight of the handrail lighter and easier to install and transport.
Color diversity: Plastics can achieve a variety of color options during the production process by adding pigments of different colors, which can meet different architectural styles and decoration requirements.
Insulation: Plastic materials have good insulation properties, which can avoid the risk of electric shock and are suitable for use near electrical equipment or in humid environments.
(II) Materials of the two-point fixing system
The two-point fixing system is mainly composed of brackets and connectors, and its materials usually include:
Metal brackets: mostly made of aluminum alloy, stainless steel or galvanized steel. Aluminum alloy brackets are light, strong and corrosion-resistant, suitable for indoor and outdoor use; stainless steel brackets are more corrosion-resistant and suitable for humid environments; galvanized steel brackets are low-cost, but require regular maintenance to prevent rust.
Connectors: Connectors are usually made of high-strength plastic or metal to firmly connect the handrail to the bracket. Plastic connectors have good flexibility and anti-aging properties, while metal connectors focus more on strength and durability.
2. Performance analysis
(I) Stability
The two-point fixing system ensures the stability of the handrail in the vertical and horizontal directions by setting two fixing points at both ends or key positions of the handrail. This design can effectively prevent the handrail from shaking or tilting during use, especially in places such as stairs and corridors where handrails are frequently used. The two-point fixing system can provide users with reliable support.
(II) Strength
The strength of plastic handrails mainly depends on the performance and wall thickness of its material. High-quality plastic materials can achieve high tensile strength and compressive strength through reasonable formula design and production process. The double-point fixing system disperses the external force to two supporting points by reasonably distributing the fixing points, further improving the overall strength of the handrail. Under normal use conditions, the plastic handrail can withstand the weight of the human body and a certain amount of external impact.
(III) Durability
The durability of plastic handrails is closely related to the anti-aging properties of their materials. Modern plastic materials can effectively resist the influence of ultraviolet radiation and environmental factors by adding additives such as anti-aging agents and ultraviolet absorbers, thereby extending the service life. The metal bracket of the double-point fixing system is also surface treated, such as anodizing treatment of aluminum alloy and passivation treatment of stainless steel, which can improve its corrosion resistance and anti-aging properties, ensuring that the entire handrail system maintains good performance during long-term use.
(IV) Installation and maintenance
The installation of the double-point fixing system is relatively simple. Usually, it only requires drilling holes in the wall or supporting structure, installing the bracket, and then fixing the handrail to the bracket through the connector. This installation method not only saves installation time and cost, but also facilitates later maintenance and replacement. The surface of plastic handrails is smooth, not easy to accumulate dust, and easy to clean and maintain. Only regular wiping is needed to maintain its appearance and performance.
3. Application cases and precautions
(I) Application cases
The double-point fixing system of plastic handrails is widely used in residential, commercial buildings, hospitals, schools and other places. For example, in residential stairs, plastic handrails can not only provide safe support, but also match the interior decoration style; in hospital corridors, the corrosion resistance and easy cleaning of plastic handrails make them ideal barrier-free facilities; in school stairwells, the lightness and safety of plastic handrails can provide reliable protection for students.
(II) Precautions
When choosing plastic handrails and double-point fixing systems, pay attention to the following points:
Material quality: Select plastic materials and metal brackets that meet national and industry standards to ensure their quality and performance.
Installation specifications: Strictly follow the installation instructions to ensure that the brackets are firmly installed and the connectors are securely fastened.
Environmental adaptability: Select appropriate materials and surface treatment methods according to the use environment, such as stainless steel brackets in humid environments.
Regular inspection: Regularly check the fixation of the handrails to promptly detect and deal with problems such as looseness and damage to ensure safe use.
