Product Uses

Grating was invented back in 1908 to solve a problem – a way to ventilate the New York subway system using open steel mesh grating. Ever since, Harsco Industrial IKG (IKG) has been designing and developing new and improved uses for metal bar grating to meet every requirement. Whether for power plants, bridges, roadways, water treatment plants, warehouses, airports, railroads or a host of other environments, IKG grating leads the industry.

We are proud to feature a few of our recent projects to illustrate some of the varied uses of our grating.


IKG’s heavy duty welded or heavy duty riveted grating is often used at airports for airplane landing ramps.  Mebac® plate products provide slip resistant surfaces for airport unloading ramps.


  • Excellent coefficient of friction (C.O.F.)
  • Durable, versatile, low  maintenance
  • Apply Mebac® once, it provides slip resistance for years

Barns, Poultry, and Livestock Facilities

Flooring made from IKG’s welded steel grating allows maximum passage of heat and air, yet allows animal waste, water and debris to fall through.  Used vertically, it serves as dividers or fencing.


  • Durable
  • Easy to clean and maintain
  • Comfortable walking surface



Heavy Industrial

IKG’s welded 19W4 grating and treads with either plain or serrated surface and a galvanized finish are the ideal products for maintenance platforms and scaffolding in heavy industrial environments such as power plants, refineries, steel mills and chemical plants.  The serrated surfaces and galvanized finishes provide extra margins of safety in areas where slip and fall loss prevention programs are important, including stairs, fire escapes, ladders, and ladder rungs.


  • Economical
  • Durable for heavy duty industrial situations
  • Low maintenance
  • High strength-to-weight ratio
  • Can be sized exactly for complex floor patterns and hard-to-fit-areas

Marine and Ship Building

Docks, wash racks and crows nests in marine environments utilize IKG products for a variety of purposes.  IKG’s Safe-T-Grid® and Mebac® Plate products are used for extra slip resistance on docks; wash racks are made from heavy duty welded steel grating to allow water and other fluids to pass through.  For crow’s nests, IKG’s Welded 19W4 Steel Grating is often specified.


  • Grating allows liquids and other debris to pass through
  • Durable, low maintenance
  • Strong

Municipal and Other Public Buildings

For public areas where uncluttered lines and architectural appearance are important, such as architectural grille work, grates, screens, fencing, dividers, awnings, IKG’s aluminum grating products, including swage-locked and pressure locked grating, are aesthetically pleasing  yet allow light, heat and air to pass through. Flush Top Aluminum Grating provides a comfortable, flush walking surface.  IKG’s Safe-T-Grid® offers a unique walking and standing surface that is ideal for entrance mats as well as sunscreens or facades.


  • Clean, architectural appearance
  • Allow maximum passage of air, light, heat
  • Versatile
  • Easy to maintain
  • Excellent lateral support


Railcar welded steel grating is engineered by IKG to exact specifications for all types of general and special purpose railcars.  Their rugged assembly provides high strength-to-weight ratios and high resistance to torsional stresses and strains for railcar running boards, freight car flooring, refrigeration car trays and train roof walkways. Extra measures of safety are provided by serrated top surface bearing bars.

Ventilated storage bins and crating for rail transported materials are manufactured from IKG’s lightweight, Swage Locked aluminum grating.


  • High strength-to-weight ratio
  • Designed to last the life of the car
  • Virtually maintenance free
  • Maximum open area minimizes ice, sleet and snow hazards



Roadways and Bridges

Engineers select IKG’s heavy duty riveted or heavy duty welded grating for situations where there are heavy or highly concentrated turning and rolling loads on bridges, bridge decks and roadway centerline markers, where drainage is important, or for trenches and inlets.  


  • Increased lateral stability
  • Durable
  • Economical
  • Low maintenance
  • High strength-to-weight ratio
For bridge walkways, where secure footing is important, IKG’s Mebac® plate or Safe-T-Grid® products are used. For maintenance access walkways, welded steel grating is used.


Sidewalk and Subway Grating

IKG’s Swage Locked I-Bar and Rectangular Bar, as well as Close Mesh Pressure-Locked and Riveted walkway grating have been manufactured for over 60 years and installed as sidewalk and subway grating in most major cities.  They are also used as vertical architectural screens or dividers


  • Reliable, proven products for heavy pedestrian traffic
  • Flush-top walking surface
  • Strong, durable
  • Maintenance free

Sports Facilities and Arenas

Fencing made from IKG’s welded steel grating or aluminum/stainless steel swage-locked grating combines lightweight and durability with an architecturally pleasing appearance.  Catwalks are usually made from IKG’s lightweight welded steel grating.   


  • Low cost
  • Lightweight
  • High strength
  • Slip resistant bearing bars



Warehouses/Sort Facilities

Mezzanine gratings are perfect for material handling applications in record and information storage buildings, sort facilities and distribution warehouses.  IKG’s lightweight 19W4 welded steel products for mezzanines are  1/8” thick, in depths of 1”, 1 ¼”, and 1 ½”.  A plain surface is suitable for rolling loads. IKG is the only company to offer GrateCoat ™ powder coat as the standard finish on its mezzanine products.


  • Economical;  long life expectancy
  • Substantial load bearing capacity
  • Comfortable walking and rolling surface
  • Reduces structural support requirements
  • Ease of installation and design
  • Allows for maximum passage of light and air

Other industrial uses for IKG products include safety screens around window, vault and machine covers.  Here IKG’s close mesh grating provides an extra measure of safety.


Water and Wastewater Treatment Plants

For maintenance platforms, stairs, ladders and scaffolding, scuppers and grates in corrosive environments such as water and wastewater treatment plants, IKG’s aluminum swage-locked grating is the usual choice.


  • Lightweight
  • Relative corrosive resistance
  • Economical
