How to Protect Steel against Corrosion

When it comes to protection of corrosion to iron or steel, the answer is galvanization. A Steel Structure normally suffers reparation, scratches or is rewelded in certain areas (after being galvanized). These usually contaminate the whole piece. A fastest and easiest way to protect these areas is adding layers of Zinc Paint.

This rich zinc coating is also known as Cathodic Paint Protection. Its main objective is to stop oxidation through a self-sacrifice mechanism, preventing oxidation in areas where previous coatings were damaged.

When properly formulated, it guarantees protection and prevents additional expenses of further coatings to steel surfaces that are exposed to corrosive environments. This is achieved through the use of a very fine zinc dust that is dispersed in a binder (normally one type of resin) completing an electrochemical cell when applied on steel.

How to apply it? Since rich zinc paints have to be in direct contact with steel you have to clean the desired area to be protected. During the cleaning process, is recommended to sandblast the area to ensure the removal of remaining paints or rust. Otherwise, impurity acts as a non-conductor affecting the proper adhesion and protective action of paint into steel.

Zinc Paint should be applied in the structure immediately after being sandblasted. It can also be sprayed. Make sure that the selected brand of paint offers triple protection (short and long term, and against abrasion) and that’s it, once again you have protected steel from corrosion.

Applying Zinc Paint on Structural Steel such as Steel Bar Grating ensures high protection and abrasiveness.  You can learn more of the Benefits of Galvanized steel Structures.

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.
