Special equipment and manufacturing techniques are employed to ensure that maximum strength and durability are built into every steel and aluminum grating bearing the Flowforge and Fisholow names. Flowforge steel gratings are forge welded, a system in which Fisher & Ludlow was a pioneer. In this process the bearing and cross bars are permanently forged together by heat and pressure into a single unit construction which results in greater strength per pound than mechanical assembly methods. Fisholow Galok aluminum gratings employ a unique interlocking system that joins the bearing and cross bars together in panels of exceptional rigidity and strength.Flowforge and Fisholow products may be found in places as far afield as the Orient and South America, and in environments as diverse as the arctic or the tropics.Whether plying the oceans of the world or drilling miles beneath the Earth s surface, buyers rely upon our gratings to perform flawlessly in the broad range of conditions under which they are employed. Specific applications include: mining and smelting operations, power generating stations, oilfields and refineries, chemical plants, water treatment facilities, pulp and paper producers, transportation equipment, commercial buildings, security institutions, shopping malls, etc.
