Expanded Steel Gratings
General Introduction to Expanded Steel Grating
Expanded steel grating is a type of steel grating that has been expanded to create a diamond-shaped opening in the middle.
There are many types of expanded metal grating, but the most common is the raised expanded metal grating. This is made by cutting slits into a metal sheet and then stretching the sheet out to create a raised, grid-like pattern. Expanded metal grating is used in a variety of metal applications because it is strong, slip-resistant, corrosion-resistant, lightweight, and versatile. It is also easy to install, has an excellent load-bearing capacity, and has a very long lifespan.
Our expanded steel gratings allow air, sound, light, and heat to pass freely and can be used for heavy-duty fences, water treatment plants, bridge walkways, barrier construction, and industrial plant construction.

ChinaGratings gives you countless reasons to choose expanded steel gratings for metal applications. They are strong and durable, lightweight as well as easy to install, clean and maintain. They are also slip-resistant and fire-resistant. Expanded steel gratings are an excellent choice for many applications.
We manufacture our expanded steel gratings using the latest technology, ensuring that we provide the best quality possible.
Our expanded steel gratings are used for many purposes, including industrial and commercial applications and residential construction projects such as catwalks, maintenance platforms, elevated walkways, security fencing, industrial stairs, window protection, and doors.
Expanded steel gratings are manufactured from carbon steel, aluminum steel, galvanized steel, or stainless steel, increasing their durability and corrosion resistance by reducing their weight and increasing their strength. They also have a higher degree of flexibility than regular steel grating, so they can be installed anywhere without causing damage to the surrounding area.
Our expanded steel gratings come in various designs, so they’ll fit your needs perfectly. We can even make custom grating sizes if you need them!
Types of Expanded Steel Gratings
Standard Expanded Steel Grating
Our regular expanded metal grating is also known as “Raised expanded metal grating” due to its unique die-cut raised surface, which is formed by the process of slitting and stretching metal sheets.
This type of expanded metal grating features a diamond opening with a rough surface and increased rigidity, making it ideal for industrial applications with limited public contact but a need for high strength.
They are available in different materials; carbon steel, aluminum, or stainless steel. Besides, you can also choose between different gauges, opening sizes, fabrications and finishes.
Expanded Steel Catwalk Grating
This Expanded Metal Grating is specially designed for catwalks and serves as the most economical and lightweight alternative to traditional maintenance platforms and catwalks.
It is manufactured using the best metals, such as carbon steel, stainless steel, aluminum, or galvanized steel. This metal sheet undergoes a stretching and slitting process to achieve ultimate rigidness, strength, corrosion resistance, and load-bearing capacity.
Our Expanded Metal Catwalk grating is available in Hexagonal and Diamond designs with different opening sizes. Besides, you can also choose between different fabrication and finishes to get the most reliable grating for your residential, commercial, or industrial settings.
Flattened Expanded Steel Grating
We have engineered flattened expanded metal gratings to fulfill the need of a wide array of architectural and industrial settings with a lot of human or animal traffic. It is suitable for making metal guards, fences, panels, grilles, screens, walkways, etc.
We have produced these gratings by reducing the thickness of the metal sheet and stretching it through a cold-roll reduction mill process. This gives a strong, durable, flat, even diamond surface.
Our flattened expanded steel grating is economical, extremely versatile, durable, and easy to install, clean, and maintain.
This type of expanded steel grating is available in different opening sizes, gauges, and materials.
The Process Flow & Duration Estimation for Expanded Steel Gratings
Step 1: Design Consultation
Our design experts have a detailed conversation with the client to determine their application needs, whether they want to use our grating as a ramp, catwalk, walkways, platform, or something else.
The design direction, expended metal type, percentage of open area, opening shape, primary material, product size, form and quantity, finishing, style, accessories, and any special requirements are also considered.
This design and consultation process usually takes 1 to 2 days.
After the order details are finalized, the client has to pay an upfront amount and sign a contract agreement to confirm the order.
Step 2: Raw Material Preparation
After the order is confirmed, our dedicated team sources high-quality raw materials from our reliable, sustainable, eco-friendly suppliers. The raw material is then thoroughly inspected to meet international quality standards. The raw material procurement process usually takes 1 to 2 days.
Step 3: Manufacturing of Expanded Steel Gratings
The manufacturing process of expanded steel grating varies from type to type.
For Example, raised expanded steel grating is manufactured using a slitting and stretching process. This process involves a die with upper and lower jaws. The metal sheet is passed between the jaws to slit and stretch the sheet to form a uniform diamond pattern.
In contrast, Flattened expanded steel grating is produced by passing a metal sheet between the rollers in a rolling mill.
After expanded steel gratings are manufactured, they are coated with the required finishing and applied with edge treatment.
Besides, other metal plates are also cut and welded on the grating’s borders.
This process usually takes 5 to 8 days.
Step 4: Finalizing and Inspecting the Product
Once expanded steel grating panels are complete, necessary cuts and holes are punched into it for screws that are required in installing the grating.
Finally, the QC team thoroughly inspects each grating panel to ensure it’s flawless and meets our quality standards.
This step usually takes three days.
Step 5: Shipping
After inspection, our expanded steel gratings are adequately packed with high-grade packaging material to avoid damage during transportation. Each grate is wrapped with a plastic film for packing, then placed in a crate or box. The empty space inside the box are filled with Styrofoam to prevent grating movement and damage. The box is then taped and labeled with shipping details.
The packaging process usually takes one day, while shipping can take 5 to 45 days, depending on the client’s location and shipping method.
