Grating
MeiseGrate is a trusted brand offering high-quality metal open bar gratings, designed for superior load-bearing capacity, lightweight efficiency, and optimal transparency. The precision-engineered connection between bearing bars, cross bars, and the surrounding frame ensures a structurally robust and visually appealing solution for various applications.
MeiseGrate metal gratings are typically manufactured from steel, stainless steel, or aluminum, but alternative materials can be provided upon customer request for specific needs.
Types & Applications
There are two primary types of metal gratings:
– Press-Locked Gratings: Mechanically interlocked for a smooth finish and uniform appearance.
– Press-Welded Gratings: Fused at high temperatures for superior durability and strength.
These gratings are widely used in walkways, platforms, machine rooms, roofing, shielding, drainage covers, and sun protection systems. Additionally, our heavy-duty gratings offer high stability and safety, making them ideal for demanding environments such as airports and truck passageways, where large support spans and high wheel loads are required.
Explore the reliability and versatility of MeiseGrate metal open bar gratings—crafted for strength, efficiency, and long-term performance.

Barefoot grating
The thing is, though, there are shoeless areas where grating can come in pretty handy — at swimming pools, for instance. Reason enough for MeiseGrate to develop a grating which is even pleasant on the naked foot!Bearing bar measurement:
30 x 2mm up to 60 x 2mm
30 x 3mm up to 60 x 3mmThe cross bar is flat-pressed U-shaped banding. The clearance between these treads is around 6 or 14mm.
Barefoot gratings can be supplied in steel, hot dip galvanised or powder coated.Quick View -
Comb gratingComb gratings are enclosed pressure locked gratings, with crossbars which protrude above the surface of the grating. The cross bars are pressed into the notched bearing bars on center-to-center spacings of 11,1 mm, 16,65 mm and 22.2 mm. The standard spacing between the bearing bars is 100 mm, but can be varied to suit the end users loading requirements. The length of the span (the direction of the bearing bars) can be up to 500 mm. The gratings are designed for ”pedestrian access”.
Scope of application:
MeiseGrate Comb Gratings are suitable for various applications:
.Facades, such as sunscreens, drainage channels and air grills.As ventilation grilles used in air conditioning and heating engineering, on inlet and outlet elements of air conditioning and heating units.As covers for overflow channels, in swimming poolsSurface treatment of Comb Gratings

Finned GratingFinned gratings are both decorative and practical. Which is why they are suitable for all kinds of purposes. As a rule, they are used as shaft covers for underfloor convection heating and as overflow channels at swimming pools.
Finned gratings can be supplied in a variety of material, profile and colour.

Full grating bear this name because the bearing and cross bars have the same cross-section and are therefore of equal height. A bearing bar is one whose ends are both supported and whose underside is not slotted. The advantage compared to the normal press locked grating is its improved screening and the attractive design.

This is press locked grating with particularly deep and/or thick bearing bars. The dimensions of the cross bar are adapted accordingly. From the name you can guess the intended application of the MeiseGrate heavy duty grating. This is press locked grating with particularly deep and/or thick bearing bars. The dimensions of the cross bar are adapted accordingly. Counter gear teeth during the pressing process gives the MEISER heavy duty grating additional stability, so that surface loads of more than 50 tonnes and wheel loads of 10 tonnes can be withstood without difficulty. We adapt the exact design from case to case to the width between supports and the intended use. Production in high-grade steel is also possible.

Press Welded I-Bar GratingI Bar Press Welded grating is a type of press welded grating made of I Bar as bearing bar and square twisted bar as cross bar. As well, I-Bar Gratigs are banded with Flat Bar or at customers’ selection with Angle.
I-Bar grating is visually stronger and comparatively lighter than Flat bar grating if bearing bars at the same clear pitcch.

Louvre gratings will always find a use wherever people don’t want other people to peer through — on bridges, gangways, elevated walkways, ventilation grilles, balconies with sun shield function and building exteriors.
Meiser produces louvre gratings from steel, stainless steel and aluminium. Here the cross bars are inserted into the bearing bars at an angle of 30° or 45° before being welded.
If requested, we can process other materials. Other mesh spacings and material dimensions also customisable … just give us a call! Louvre grating can be produced to a height of 100 mm.

Offshore-gratings (O-SP-SS)
As its name suggests, offshore grating was originally developed for use on offshore oil rigs.Basically a press welded grating, it is strengthened by round bars welded beneath the twisted cross bars and in the same direction as the bearing bars. See the photo to the Left.

30 x 19mm with a round bar welded beneath so that a test ball 15 mm in diameter cannot fall through.Bearing bar measurement:

MeiseGrate press locked gratings are usually made of steel, stainless steel or aluminum. However, other materials can be used if the customer so wishes.
On the computer controlled production lines, the bearing bars are notched and, at the same time, locked with the non-attenuated cross bar and weld both together afterwards
This particular production method guarantees a uniform precision mesh size. The edge of the press locked gratings is banded either with T-shaped special section or flat bar. This process i.e. where the banding is welded at right angles to and flush with the grating surface is effected on an automatic bordering machine via resistance welding.
Maximum cross bar length
2900 mm bearing bar 2-3 mm
2300 mm bearing bar 4-5 mmMaximum bearing bar length
Although production method does not set any limits here, in practice the length will be predetermined by statical requirements and unit weights.End meshing
End meshes opposite one another are the same size. Customised solutions also possible on request.Bearing bars
In parallel with one another from one rest to the next, the bearing bars are the load carrying flat bars set out perpendicularly.Cross bars
At right angles to the bearing bars, the cross bars connect the bearing bars with one another in that they are pressed and/or welded at the intersection pointsQuick View -
Press welded gratings are produced from steel. The bearing bars (I-Bar or Flat Bar) and the twisted square cross bars are cut to grating size before the cross bars are locked into the bearing bars at a pressure of 1000 kN and – simultaneously – electrically welded at 2500 KVA. Into one unit.
In combination with welded cross bars, non-attenuated bearing bars make for high torsion rigidity.
Press welded gratings are banded with flat bars which, as a rule, will have the same cross section as the bearing bars.
One special form of press welded grating is offshore grating (O-SP-SS), details of which you will find on special forms of gratings. Due to the way the bearing bars are profiled, press welded gratings have a much enhanced anti-skid capability. Please see (anti-skid gratings).

The ultra-grating is a welded and press locked grating. First the cross bars are bonded with the bearing bars and then welded together as well. This technology provides extra stability even without edge banding.
Meiser produces ultra-grating in standard panels for machine shops and fitter’s shops for further processing.

A special form of press-welded gratings are in 6000 x 1000 mm mats, with a perforated sheet welded between the bearing bars. The 1,2 mm thick perforated sheet has 8×8 mm square openings spaced at 4 mm intervals and is manufactured with a profiled edge for resistance welding.Quick View
