Metal railings are safety and design solutions for stairs, balconies and terraces. They can be made of different materials such as stainless steel, aluminum or wrought iron, and are available in various styles, from modern and minimalist to more elaborate and decorative ones..
In addition to providing protection, metal railings can also contribute to the aesthetics of a building or interior environment.
They offer different advantages over other materials, including:
Durability: They are extremely resistant to penetrations, scratches and impacts, maintaining their integrity over time • Minimal maintenance: They require no special cleaning or maintenance procedures, making them practical and convenient
Corrosion resistance: Stainless steel is rustproof, so metal railings are ideal for both indoors and outdoors, resisting adverse weather conditions well
Lightweight: Despite their strength, metal railings are relatively lightweight, which facilitates installation and reduces strain on the supporting structure
Versatility: Can be customized in terms of color and shape, adapting to a variety of architectural and design styles
Aesthetics: They offer a modern look and can be combined with other materials such as glass or wood to create unique designs
These factors make them a popular choice for many construction and renovation projects..

During assembly they can be fixed to the floor or to the load-bearing structure through various methods, depending on the type of flooring and structural specifications.
Here are some of the common methods:
Chemical anchors: These are often used to attach guardrails to concrete floors or other solid surfaces. Threaded rods cut to size are inserted into the holes filled with chemical resin, which then hardens creating a solid anchor
Clamps: Can be used to secure railings without having to drill into the floor, ideal for surfaces where drilling is not possible or desirable
Welding: In some cases, they can be welded directly to the supporting structure, especially when they are made of steel or other metals compatible with welding.
Screws and bolts: For wooden structures or other surfaces that can be drilled, screws and bolts are used to attach the guardrails.
It is important to follow current regulations and best safety practices when installing metal guardrails, to ensure they are secured correctly and are able to withstand the forces applied.
Testing the stability of metal railings after installation is an important process to ensure safety. Here are the general steps that are followed:
1. Visual Inspection: Check that there is no visible damage and that all components are installed correctly.
2. Fixing Check: Ensure that all fixings, such as chemical anchors, clamps, screws and bolts, are tight and show no signs of wear
3. Load Test: Carry out static and dynamic load tests, such as the pendulum test, to verify the mechanical resistance to loads
4. Regulatory Verification: Compare the installation with current regulations, such as EN ISO 14122-3:2016, to ensure that all specifications are met
5. Documentation: Draw up and keep the documentation relating to the installation and tests carried out, including any certificates of conformity
It is advisable that these checks are carried out by qualified professionals to ensure maximum safety..
