Common metals for grating include iron, carbon steel, aluminum, and stainless steel, typically used for non-slip applications requiring secure platforms.

metal gratings come in various patterns and designs, including steel grating-plate combinations. Production methods like welding, press-locking, or metal plate integration ensure durability in demanding environments.

Chapter Two – Types of metal Gratings

Engineers and designers create functional metal grating solutions tailored to load-bearing, safety, and environmental needs. Key specification factors include thickness, surface area, load capacity, span, bar dimensions, panel size, and opening patterns (oval, square, diamond) that impact industrial and architectural performance.

Additional design considerations include light transmission, ventilation, drainage, acoustics, aesthetics, and slip resistance. Heavy-duty applications often use welded steel or pressure-locked bar grating for strength in manufacturing plants and chemical facilities.

Expanded metal Gratings

Expanded metal grating features a diamond-shaped mesh created by slitting and stretching metal sheets, offering rigidity without welding. Made from carbon steel, stainless steel, or aluminum, it suits indoor/outdoor and corrosive environments.

Standard versions provide slip resistance for walkways and platforms. Flattened types offer smooth surfaces for foot traffic, while raised versions enhance traction for safety-critical areas.

Bar metal Grating

Industrial bar grating consists of parallel load-bearing bars connected by cross bars via welding, press-locking, riveting, or swaging. Welded versions provide maximum rigidity for industrial flooring and catwalks.

Material selection (galvanized steel, stainless steel, aluminum) depends on load, environment, and corrosion needs. Its strength-to-weight ratio and open design make it ideal for trench covers, stair treads, and bridges.

Wire Mesh metal Grating

Wire mesh grating features intersecting wires in grid patterns, valued for adaptability and strength. Welded versions offer structural integrity, while woven types provide flexibility.

Used for machine guarding, fencing, and filtration, stainless steel versions resist harsh environments.

Perforated metal Grating

Perforated grating contains precision-cut holes in metal sheets, offering strength and slip resistance. Applications include industrial flooring, architectural facades, and filtration systems.

Safety Grating

Safety grating features diamond/serrated patterns for slip resistance in industrial settings. Designs allow drainage and airflow, meeting OSHA standards with galvanized or stainless steel construction.

Compound metal Grating

Combining bar grating with checkered plates, compound grating increases traction and load distribution. Ideal for industrial platforms and bridge decks.

Press Locked metal Grating

Press-locked grating features notched bars pressed together for seamless surfaces. Used in architectural projects requiring both strength and aesthetics.
