Description
Product Introduction
Press-locked (press-welded) bar grating with cross bars pressed into deep slots for a flush, smooth-top panel. Bars 3/4" to 4" deep in galvanized steel, aluminum or stainless. Clean lines for facades, sunshades, walkways and screens.
Overview
Press-locked bar grating, sometimes called press-welded grating, forms its joints by pressing cross bars into deeply notched slots cut in the bearing bars under heavy hydraulic force. Both members sit flush at the top, producing a smooth, even surface free of protruding rivets or weld beads. The result is a rigid yet refined panel prized for architectural and high-visibility applications as much as for industrial use. Press-locked grating accepts carbon steel, aluminum and stainless steel, and its clean geometry suits facades, sunshades, screens and feature walkways. Bearing bars from 3/4" to 4" deep let the same elegant joint serve decorative screening or functional load-bearing decks, giving architects and engineers a single product line that bridges appearance and structural performance.
Construction & Materials
Bearing bars 3/4" to 4" high and 1/8" to 1/4" thick are slotted to receive the full-height cross bars, which are then pressed home so both bar tops finish in the same plane. This interlocked, two-way bar layout creates a uniform, grid-like face on standard 19-W-4, 15-W-4 and 11-W-4 spacings. Hot-dip galvanizing protects carbon-steel panels outdoors, while aluminum offers light weight and a mill or anodized finish, and stainless delivers premium corrosion resistance and a bright architectural look. Panel widths of 24" and 36" run to lengths up to 288", with edge banding and custom borders available. Because cross bars are flush rather than welded on top, press-locked panels can be powder-coated evenly and present a continuous, attractive surface from above and below.
Performance & Standards
Press-locked construction provides high panel rigidity with load capacities documented in standard load tables by bearing-bar size and span. Open area ranges from roughly 20% to 89% according to spacing, allowing designers to tune airflow, light transmission and visual transparency for screening and sunshade duties while still supporting walkway loads. Serrated bearing bars add slip resistance where panels double as walking surfaces, and close-mesh ADA layouts suit pedestrian access. Galvanizing, anodizing and powder-coat finishes meet relevant durability and appearance standards. For structural floors, concentrated and uniform load tables confirm the right bar depth and span; for architectural screens, the same panels are specified for wind load, shading coefficient and visual porosity, making press-locked grating equally at home in engineering and design-led projects.
Applications
The flush, smooth-top face makes press-locked grating a favorite for building facades, sunscreens, balcony rails, fencing infill and security screens, where appearance matters as much as function. The same panels serve practical roles as walkways, platforms, mezzanine decks and equipment access flooring. Architects use the regular grid and adjustable open area to control daylight, ventilation and sightlines on parking structures, transit stations and commercial buildings. In industrial settings, press-locked panels provide stable footing on plant walkways and stair landings, with serrated options for wet or oily areas. Aluminum and stainless versions perform in coastal and corrosive environments, while galvanized steel covers general outdoor service, letting one product family cover decorative cladding and load-bearing access throughout a single project.
