Types of Steel Bar Grating

What does Steel Bar Grating is?

Also known as bar grating or just Grating, which is produced through the electroforged process. This consists in welding steel cross rods to perpendicular and equidistant bearing bars. This is achieved through high current and high mechanical pressure discharges, fusing the molecular elements of both components without placing filler material, as it occurs in the arc welding process. The forged welding process guarantees an homogeneous product of high quality and resistance.

The standard panel is normally made of 34 bearing bars.

Several Types of Steel Bar Grating exist, each of them satisfy different construction purposes:

  • Heavy Duty Grating, commonly used at airports and in  heavy transit locations.
  • Stainless Steel Grating, it is mainly used in food industry plants and sulfate or acid environments.
  • Galvanized Steel Bar Grating, ideal for any type of use, its finish ensures a longer lifespan of up to 60 years.
  • AAR M-1003, grating used for running boards in the railroad industry. Manufacturer must fulfill certification.
  • Architectural Grating, used in residential, urban and commercial projects as faÁ§ades, benches, balconies, fences, tree guards and as many other applications.

Quality and durability of the materials used in a construction project are important, but so is its design. Custom Fabricated Grating is an excellent alternative to ensure specific cuts and aesthetic, but also facilitates installation.

No matter what your project is, Steel Bar Grating is a good option to reduce costs and maximize durability due to the different applications that features. Seek a good installation avoiding The 4 most common mistakes in Steel Bar Grating Installation.

Steel Bar Grating Certifications

Any project should ensure quality in its construction materials. Quality is so important to client satisfaction  that steel bar grating manufacturing companies seek to obtain fabrication process certifications in order to supply the highest possible quality.

These certifications are established by international organizations whose objective is to standardize requirements throughout the world regarding quality management:

    ISO 9001 certification guarantees national and international clients that its manufacturer meets the required quality standards and regulations by the market.
    Laboratorio de Pruebas Equipos y Materiales is a Federal Electricity Commission organization in Mexico that aims to address the needs of the power sector nationally and internationally. LAPEM Certification allows the manufacturing companies to provide galvanized products and services to the Commission.
  • AAR M-1003
    The Association of American Railroads in its specification M-1003 Section J for quality assurance, points out the requirements to be met for reliable suppliers of the AAR. AAR M-1003 Certification enables companies to provide Steel Bar Grating running boards to the rail industry.

Steel Bar Grating Manufacturing Companies should also consider being members of specific associations that are committed into best practices:

    Since 1938 the National Association of Architectural Metal Manufacturers has represented a wide variety of architectural metal products for building construction. Its objective is to contribute manufacturing companies specific technical standards promoting quality in the market.
    Stands for Mexican Association of Galvanizers. It is a nonprofit organization whose main objective is to promote and develop a galvanizing culture in the country. Hot Dip Galvanizing offers great benefits to steel products, if you wish to learn more about the importance of the galvanizing process, we suggest reading Benefits of Galvanized Steel Structures.

A high quality product flattered by the international market appears whenever the manufacturer understands that it has to be certified in its production processes and also joins as a member in the previously mentioned associations.

Several Types of Steel Bar Grating exist, each one of them has different characteristics in order to satisfy the necessities of the desired covered area. Their functionalities vary depending on the possible loads, uses and environments in which the grating is going to be installed.

Achieving Resistance and Safety on Industrial Floorings

When planning large projects such as industrial plants, commercial buildings or offices, you usually seek to obtain the highest quality in every single aspect. Personnel transiting during operation requires a safe working environment. In this article, we’ll explain how to achieve greater Resistance and Safety on Industrial Flooring.

Industrial Flooring should be designed to withstand some of the following types of loads:

  • Pedestrian Transit
  • Vehicular Transit
  • Specific Point Loads

It is highly recommended that at the beginning of the project, both, constructor and industrial flooring contractor (oil platforms , water treatment plants , chemical plants , bridges , airports , power plants, livestock facilities), request the necessary information that will help them to guarantee security and quality to working areas.

Budget is probably the most important variable to consider when choosing the product to be used as Industrial Flooring . For this decision, you must take into account the initial cost, maintenance costs and service life.

When thinking of substituting solid floorings, Steel Bar Grating is a great choice to replace them. Common cases:

  • Areas requiring the flow of: light, heat and sound
  • High vibration areas
  • Areas that should not accumulate gases or liquids
  • Antiskid flooring
  • Easy installation
  • Adaptability to complex patterns of the future covered area (Custom Fabricated Grating)
  • High ratio Load-Weight
  • Nonmagnetic, non-sparking and corrosion resistant flooring (Hot Dip Galvanizing)

It is important to notice that Steel Bar Grating offers its maximum resistance only if it is properly installed. Therefore we recommend reading Top 4 common mistakes in Steel Bar Grating Installation, to ensure a longer life to your project.

4 most common mistakes in Steel Bar Grating Installation

Steel Bar Grating

ensures better performance than other type of Industrial Floorings in industrial and Architectural Projects. Its functionality depends directly on its installation. When this is not carried out in a good way, its durability, strength and aesthetic are normally affected.

After the assembly, is common to identify installation mistakes. Since reparation is expensive, the key is to avoid them being cautious in small details.

We have enlisted the 4 most common mistakes in Steel Bar Grating Installation, so we expect you to take this into account in your next Grating project.

1.- Bearing bars pointing at wrong direction

The key to avoid this mistake relies on the bearing bars. They must point out to the shortest distance of the desired covering space. When this is done wrongly, cross rods normally bend down triggering a poor loading capacity. A well placed Trench Drain is safe for pedestrians, and acts as an extension of the street for heavy transit.

2.- Missing banding on bearing bars edges

It is important to include banding on the grating edges to avoid unnecessary welding and broken edges. Banding also helps transferring burden to unloaded bearing bars assuring the grating´s capacity.

3.- Placing the Steel Grill upside down

As shown in the picture , it should face the side in which the load will be received, same side in which cross rods can be seen.  In the contrary, you run the risk of bending or breaking the bearing bars, causing loss of loading capacity, and making it dangerous to those who transit over it.

5.- Unaligned cross rods

Proper cross rods alignment shows professionalism of who installed it. Gives better appearance, and helps transferring load evenly throughout the piece. To avoid this mistake, we suggest asking your supplier for Custom Fabricated Grating.

These are the 4 most common mistakes in Steel Bar Grating Installation. We hope our guidance will help you to obtain the best of grating on your projects. Reduce unnecessary costs from product replacements, and ensure its functions for many years.
