A common type of grating is the Type R pressed grating.

Besides traditional walkway applications, this type

is particularly suitable for use in utility buildings as

façade cladding, sun shading, balcony fencing or

partition walls.

the type R pressed grating is constructed from bearing

bars into which transverse bars (10 x 2 mm) are pressed.

the grating panel is finished with a profiled thielco frame

strip and then undergoes hot-dip galvanizing in-house.

Pressed gratings can be produced up to a bearing bar

length of 3,000 mm and a transverse bar length of

1,750 mm.

Anti-slip serrations

For situations with an increased risk of slipping, panels

with anti-slip serrations are available. Because both the

bearing and/or transverse bars are serrated, an extremely

high degree of grip is achieved on the grating surface

(single anti-slip with serration on the bearing or transverse

bars, double anti-slip with serration on both the bearing

and transverse bars).

The SP type grating is constructed from bearing bars

and forged transverse bars. during the production

process, the transverse bars are welded to the bearing

bars at every joint under high pressure and current.

A mesh width of 34 x 38 mm with approximately 800

welded joints per m2 gives the grating high stability and

load-bearing capacity. this type is ideally suited for heavy

to extremely heavy loads.

Gratings exposed to pollutants such

as oil, grease, snow or ice are available

in anti-slip versions. Small moon-

shaped serrations are made in the

bearing bars, enabling optimum

contact between foot and grating.

This makes slipping virtually

impossible.

Type SP Ball Proof safety grating

For special safety regulations, thielco

supplies so-called Ball Proof gratings

made to measure. For personal safety in

the offshore and petrochemical industry

it is a general safety requirement that

objects of 15 mm or larger should be

unable to fall through the grating.

Safety is guaranteed by welding an extra

wire of 5 mm rounded steel underneath.

the wire welded underneath is placed

between the bearing bars and is

automatically welded against the

underside of the forged bars.

these gratings are available in smooth

and anti-slip versions.

For some applications where an open grating is not

desirable and anti-slip is required, the use of a

perforated grating is a better option. The treads and

platforms are manufactured in 3 mm thick steel plate.

Perforated treads for outdoor use are characterized by

upwardly punched flat holes to provide anti-slip and water

drainage (type tP 350w and tP 340w).

Perforated treads for indoor use are characterized by

upwardly punched holes to provide anti-slip (type tP 350)

or flat holes with or without rubber plugs (type tP 350 D).

these treads are available as (not galvanized) welded

treads without end plates and as galvanized treads with

end plates for mounting between the stair stringers. Special

end plates are available on request. it is also possible to use

these treads for spiral stairs in every desirable form.

Thielco itself provides the surface treatment of its own

products but also galvanizes all kinds of products for

third parties, such as the steel construction industry,

the fencing industry, the trailer and semi-trailer

construction industry, machine building industry, etc.

Thielco keeps production in-house from start to finish.

This service has seen rapid growth in recent years.

hot-dip galvanizing

hot dip galvanizing products guarantees maximum

protection against corrosion. Maximum resistance to

mechanical loading is achieved by alloying the zinc with

the steel.

hot dip galvanizing is a dipping process in which fluid zinc

must penetrate all recesses, open and hollow components

and constructions. in order to achieve this, it is important

that there is sufficient flow into and out of openings to

permit de-aeration and through flow. these openings

need to be properly located and be large enough not to

inhibit the flow. the protective layer applied by hot dip

galvanizing is thicker than other protective layers. to hot

h Ot - d i p g a lVa n i z i n g

dip galvanize hinged sections, depending upon the

thickness of the material, it may be necessary to leave

1 to 3 mm free.

Sufficiently large openings increase the flow of the fluid

zinc into and out of the construction or components and

increase the dipping speed. this prevents deformation and

enhances the quality of the zinc layer. After galvanizing,

the holes are sealed with aluminium, lead or plastic plugs.

Galvanizing bath dimensions

9,000 x 1,500 x 2,700 mm

continuous strict quality control and collaboration with

zinkinfo Benelux ensure guaranteed quality. Galvanizing is

carried out to nen and iSo 1461 standards or to your

specification.

For specific information regarding de-aeration, brands,

welds, deformations, suspension holes or crane hooks, we

will be only too pleased to advise you in person.

it is increasingly common for hot dip galvanized

materials to be given an additional organic layer

(powder coating). Architects, product designers and

advisers are continually in search of decorative colour

applications for steel. hot dip galvanizing and powder

coating with one or two layers makes an interesting

range of decorative and colourful applications

possible. it is even possible to powder-coat two layers

in a single procedure.

the complete process of surface treatment takes place

in-house, making thielco a reliable and expert partner in

surface treatments. thielco is able to pre-treat products

chemically and mechanically. the process is

environmentally-friendly due to the use of a modern

chrome-free polymer technology. Products up to 10,000 x

600 x 2,400 mm can be chemically or mechanically pre-

treated. we recommend applying a two-layer system to

the products after galvanizing. the first layer is an epoxy

primer, the second is the colour (polyester powder). the

total layer thickness is approximately 120 microns. thielco

works in accordance with the Visem quality requirements.

Thielco has ceramic high temperature zinc ovens.

These are particularly suitable for hot dip galvanizing

of a whole variety of smaller fastening materials, such

as bolts (from m8), nuts, clips, clamps, wire nails,

threaded rods and anchors. This procedure also serves

various markets. you will find fastenings which have

been treated by Thielco not only in steel construction

and machine building, but also in the wind turbine

industry and in the automotive and energy sectors.

various qualities of steel are possible. Thielco

specialises in grades 8.8 and 10.9 among others.

Thanks to a chemical/mechanical pre-treatment and

control over the galvanizing process, there is no

danger of hydrogen brittleness.

After galvanizing the products, surplus zinc is removed by

a centrifugal process, giving a smooth and even zinc layer.

the thread in nuts and tapped holes must be tapped

again to ensure a normal bolt fit. the absence of a zinc

layer in the thread has no negative impact on the

corrosion resistance. the zinc layer on the bolt or the

thread end sufficiently protects the thread of the screw.

the modern centrifuge process allows hot dip galvanizing

of even smaller sizes of bolts and nuts without the fit

being compromised. thielco advises fitting hot dip

galvanized constructions with hot dip galvanized bolts

and nuts. our quality meets nen and iSo 1461 standards.

Moreover, thielco works according to client-specific

quality requirements.

Products with a screw thread of between m10 and m100

can be hot-dip galvanized without a problem. the screw

thread remains available over the complete length, even

up to 3,000 mm in length.

This refined metal-finishing technique produces

extremely thin protective layers of 3 to 85 microns. As

this is a cold procedure, Thielco uses this technology

particularly for small products which are sensitive to

heat, such as hardened products, steel springs, m8

bolts, nuts, mounting rings and wire nails.

the zinc layer is applied in a rotating drum. this results

in a smooth layer exhibiting excellent adhesion. An

advantage of this technology is that no hydrogen

brittleness occurs, so unnecessary breakage is prevented.

Besides zinc, other metal layers can be applied, such as tin,

copper and aluminium.

the products can be treated afterwards with a layer of oil

and/or a chromate layer to reduce the friction coefficient.

our quality meets the iSo 12683 and AStM-B 695

standards. thielco also works according to client-specific

quality requirements.

Thielco Metal Coating is iSo / TS 16949 certified. This

standard plays an important role in the automotive

sector for many years and was drawn up by the

‘international Automotive Task Force’ (iATF) and the

‘Japan Automobile Manufacturers Association, inc.’

(JAMA), with the support of iSo / TC 176 ‘Quality

management and quality assurance’. This certification,

combined with the very latest and highly advanced

production process, guarantee you the highest quality

standards in the market.

The Geomet® procedure

thielco Steel Solutions Group is the only licence-holder in

the netherlands for the Geomet® chromium-free coating

technology of noF Metal coatings. this technology offers

an environmentally-friendly alternative to the coating or

galvanizing of smaller metal products - using solvents,

mechanically or via electro-plating - particularly for the

automotive industry.

A zinc-aluminium laminated coating is applied in a fully

automated production line. this ensures extremely high

corrosion resistance at a low layer thickness. A second

important advantage is that hydrogen brittleness cannot

occur. we can describe a product as a Geomet product

once two layers have been applied because only then is

the required protection offered. A third layer, the top coat,

allows the product’s friction coefficient to be efficiently

regulated. this is extremely important for various

applications.

thanks to these production lines, thielco is able to offer

a total package in Geomet 321 and Geomet 500 with

various top coats. Products in all diameters and grades of

steel, with or without screw thread, up to a maximum

length of 850 mm. this is unique for the whole of the

netherlands. the Geomet procedure is chromium-free and

as such meets the most recent eU guidelines.
