1 ArcelorMittal Technotron s.r.o. Expanded Metal – Fliers and Framings November 2008

2 Fliers Perfect solution to cut costs for each application STRENGTH SAFETY NON-SLIP Main advantages of stair steps from expanded metal are easy maintainance, big bearing capacity with small grating weight, anti-slip effect with safe walk in woman shoes Date / time1Page Number

3 Fliers Load The permissible concentrated force acting on an area of 100 x 100 mm in the flier centre is 1500 N. To select the flier grillage type, apply the same rules as for the framing type selection. A selection procedure and example is given for floor framings Material quality Fliers are made as weldments of expanded metal, fixing plates and stiffeners. The expanded metal (3x62.5/15x5 or 3x47/13x5) is manufactured from plates of the steel qualities , , , The fixing plates and stiffeners are made from the same materials as the expanded metal, or from the steel quality plates.

4 Surface protection By customer’s request, the fliers are supplied as hot galvanized acc. to DIN 50976, raw without surface protection, varnished or hot galvanized acc. to DIN Flier mounting The flier fixing plates (side edges) are provided with circular and oval holes for screws M12 to attach the flier to the strings. Each flier has to be fixed with 4 screws. The fixing screw pitch can be adjusted by the customer’s request. Fliers ArcelorMittal Technotron s.r.o. 3Page Number Date / time

6 Framings Range of application industrial gangways, stair landings, platforms including staircases covers for drains, channels, reservoirs and shafts in the sphere of water-management elevated approaches for barrier-free entrance stair treads and barriers shelves and stock surfaces Welded products from expanded metal, circumference frame and length reinforcement Date / time5Page Number

7 Framings Material quality Floor framings are made as weldments of expanded metal, peripheral frames and stiffeners. The expanded metal (62.5/15x5) is manufactured from plates of the steel qualities , , , The peripheral frame and the stiffeners are made from the same material as the expanded metal, or from the steel quality plates. Surface protection The floor framings are supplied without surface treatment, with surface protection by hot galvanizing acc. to DIN 50976, oiled or varnished. General guidelines to select the framing type It is essential to proceed as follows: 1. determine the framing load (e.g., from the project or by means of the loading table) 2. enter the support distance, limit deflection or other binding conditions 3. determine the framing type by means of the loading tables ArcelorMittal Technotron s.r.o. 6Page Number Date / time

8 Example Setpoints: - dimensions: span (support distance) L= 750mm, non-bearing width W = 1000 mm - load: 350 kg/sqm, which corresponds to 3.5 kN/sqm - requirement: an expanded metal framing without special limitations Solution: - find the nearest satisfactory framing from the expanded metal framing loading tables - indicate the name in the order: expanded metal framing T62.5 x 15 / 3 x 5 / 30 x 3 / 800 x 1000 Note: The bearing dimension value has been increased by reason of the framing placing on the support. The framing support seating in the stiffeners direction should, if possible, be at least equal to the stiffeners height, the minimum value is 25 mm.
