Pressed / custom welded grids: elasticity and mesh versatility

WHAT IT IS

What is a pressed or welded grid?

A pressed grating is manufactured by joining two crossed crosswise by means of press-fit assemblyThe separating plate is fitted into the supporting plate to form a stable and uniform assembly.

A welded grid is based on the same plate-plate concept, but incorporates welding to form a single body. In this type, not all intersections are weldedare not welded, but welding is performed is welded diagonally and spacedspaced, which provides elasticity and helps to avoid breakage when the grid is working under load.

ADVANTAGES AND PROPERTIES

Advantages and properties of our pressed/welded gratings

Our pressing/welding gratings stand out for:

  • Mesh versatility: possibility of working more “closed” meshes according to use (for example, from 8×8 mm in certain configurations).
  • Controlled elasticity: the arrangement of joints/welds allows the material to “work” under load without behaving in a brittle manner.
  • Clean and technical finishhighly appreciated in projects where the grille is visible.
  • Reliable solution for crosswalk and maintenance (depending on plate configuration, span between supports and actual use).

Compatibility with secure fastenings and the possibility of disassembly when access to installations is required.

MATERIALS AND FINISHES

Materials and finishes available for pressed/welded gratings

We can manufacture pressed/welded gratings in:

  • Galvanized steelthe most common choice when there is exterior, humidity or corrosion protection is required.
  • Untreated steelfor interior use or when the final finish is defined on site.
  • Stainless steel 304 / 316recommended for the most more demanding environments (humid, marine, chemical or when aesthetics are important).
  • Aluminum: alternative light with good corrosion resistance in certain applications.

Quick tip: if you tell us indoor/outdoorenvironment (humid, marine, chemical) and use, we will guide you on the most suitable material.

Which pressed/welded grating to choose according to use

Use / environment Recommended option Typical material / finish For sizing, tell us...
Architecture / visible grid Pressed (plate-plate) 304/316 stainless steel or aluminum Dimensions + span between supports + load
Exterior / humidity Pressed or welded galvanized Galvanized Indoor/outdoor + environment + load
Very closed mesh (security) Pressed/welded with closed mesh Galvanized or stainless steel Risk/object + light + load
Wet or oily areas Pressed/welded + slip resistant Galvanized or stainless steel Transit + humidity/oils
Access to installations / access to installations Pressed / welded removable Galvanized or stainless steel Frequency of opening + dimensions + support
High loads / heavy traffic Validate configuration (compare with electrofusion) Galvanized Support spacing + type of load

If you indicate span between supports y type of loadwe will propose you the appropriate configuration.

DIMENSIONS ACCORDING TO LOAD AND USE

Measurements and configurations

In pressed/welded gratings, the choice is not just a matter of “size”: it depends on span between supports y type of load(pedestrian, maintenance, etc.).

Typical configurations:

  • Casting with unequal plates (load-bearing + smaller spacer): very common for balance between stiffness and mesh option.
  • Double splicing with equal platesAesthetically very uniform; if only supported on two sides, it may reduce load capacity compared to other solutions (to be assessed on a case-by-case basis).

To make a safe choice, rely on Tables and technical data (and, if you want, you can send us the data and we will validate it with you).

FREQUENT APPLICATIONS BY SECTOR

Frequent Uses

The versatility of the mesh and the technical finish make them suitable for use in:

  • Industry and maintenance: walkways, technical platforms, plant walkways, machinery access.
  • Infrastructures and services: manholes, channel covers and technical areas where ventilation and access are of interest.
  • Architecture and aesthetic integration: technical enclosures, exposed elements, solutions where a defined mesh and a more “architectural” finish are sought.
  • Logistics and maintenance centers: technical areas, pits, inspection and transit areas.
COMPATIBLE FIXATIONS

Installation and maintenance

The installation depends on the support (metal structure, concrete, frames, etc.) and whether you need the grating to be removable. removable. For a secure fixation, we work with a complete range of fastening and connecting parts (galvanized and stainless steel), where the choice depends on the mesh, height and thickness of the supporting bars.

Maintenance is usually low: periodic cleaning y visual inspection of fixings, especially in outdoor or aggressive environments (where it is advisable to choose suitable material/finish).

Frequently asked questions about pressed/welded gratings

Check out the 10 frequently asked questions about pressed / welded gratings: advantages, regulations, deadlines, loading, installation and more.

What is the difference between pressed grating and welded grating?

Pressed is assembled by press-fitting plates; welded incorporates welded joints (often diagonally spaced) to form a resilient assembly.

What is the difference between pressed/welded and electrofused grating?

It changes the process: the electrofusion process joins plate + rod at each crossing; the pressed/welded process combines plate with plate and allows other meshes/configurations.

What minimum mesh can you manufacture?

In certain configurations, the smallest mesh size indicated is 8×8 mm.

Which material is best for me: galvanized, stainless steel or aluminum?

It depends on whether it is indoor/outdoor, environment (humid/marine/chemical) and aesthetics. Podemos fabricarlas en galvanizado, sin tratamiento, inox 304/316 o aluminio.

How to choose the support plate?

With the light between supports and the load. If you provide us with these data, we recommend a secure and consistent configuration with technical tables.

Can they be made to measure according to drawings?

Yes, we manufacture custom-made panels and can consider cut-outs and machining for recesses, registers or installation passages.

What if it only supports on two sides?

Some configurations (e.g., double bonded) may lose capacity if they only support on two sides; therefore, they are validated according to supports and actual load.

What bindings do you recommend?

It depends on the mesh and the supporting structure. Fastening/jointing systems are available and the choice depends on mesh, height and thickness.

What tolerances do you handle?

They depend on the format and process. For critical fits, it is better to work with plan and final measurements, and to mark sensitive points.
