FRAMED PRESSURE LOCKED GRATINGS IN STAINLESS STEEL
Stainless steel delivers the highest quality grating material with an exceptional finish.
Horizontal applications
Prestigious flooring with specific markets in the food, pharmaceutical and chemical industries
Vertical applications
Balustrades, balconies, screening
Pressure locked gratings are constructed entirely from flat bars by pressing an arrangement of cross bars into notched bearing bars. The bars are
further secured by a choice of flat wrap-around framing bar, producing a custom-sized grating panel with perfectly formed intersections.
This manufacturing method is extremely adaptable and the production process can promptly provide grating panels in custom sizes and to non-standard
specifications of weight, aperture and performance.
Alternative grades of stainless steel:
AISI 304 for general purpose
AISI 316 for exposure to harsh substances or marine conditions

TREATMENTS FOR STAINLESS STEEL All gratings are generally subject to finishing treatments such as de-greasing, pickling and polishing to reduce surface roughness, eliminate burrs from processing and maximise resistance to corrosion. Corrosion Austenitic stainless steels have a characteristic layer of chrome oxide on the surface (created by air or produced artificially) which is very thin and invisible and which protects the material from environmental damage: this resistance mainly depends on the percentage of chrome and nickel. When the formation of this layer of chrome oxide is prevented or when this layer is continually destroyed, austenitic stainless steels will corrode. To achieve good resistance to corrosion it is therefore necessary to know the types of corrosion possible and their causes, choose the suitable alloys for each application and carefully produce a design. Finally, appropriate surface treatments need to be performed. De-Greasing An essential operation before applying any heat treatment or surface finishes (such as pickling or electro-polishing) to remove any traces of grease or dirt which could damage the material itself or could lead to spotting. De-greasing is normally done by immersion or by spraying a de-greasing agent such as FS10. When the treatment has been completed, the panels are thoroughly rinsed with cold water under pressure, which also provides a mechanical cleaning action. Pickling Pickling of the surfaces is always carried out prior to electropolishing or passivation to eliminate oxidise crusts that form on the surface during processes such as hot rolling, annealing, or welding. Pickling is done by immersion or by the application of a pickling gel. Normally the treatment is done by immersion in a chemical bath consisting of sulphuric acid (20-25%), hydrofloric acid (2.4%) and phosphoric acid (1-4%). Panels are again thoroughly rinsed with cold water under pressure. Electropolishing Electro-chemical polishing (DIN8590) creates a homogeneously polished surface by combining electrolyte solutions of phosphoric acid (30-50%) and sulphuric acid (30-50%) with electricity. The panel forms the anode of an electrolytic cell, while the cathode is usually formed by a plate in the stainless steel AISI 304. The principle is to remove material by selectively dissolving the surfaces to be treated in an electrolytic bath, under the action of the appropriate electrical current: a direct current at a voltage of 50-15V with a density usually between 0.2 and 0.5 A/sq cm. Benefits of electropolishing - reduction of surface roughness - elimination of burrs from processing - increase of the resistance to corrosion - enhancement of dirt repelling properties and aid to cleaning
