\"Painted<\/a>

Open bar grating deck surface on an observation platform.<\/p><\/div>\n

 <\/p>\n

Let\u2019s continue our exploration into the different types of decking used on our mezzanines<\/a>.\u00a0 Last time we talked about corrugated roof deck with resindek.\u00a0 We mentioned that as a wood composite material it can swell if soaked, so it is not the ideal deck type for wet environments.\u00a0 Today we\u2019re going to talk about one deck type that excels in wet environments:\u00a0 open bar grating.<\/p>\n

The typical grating that we use is a 19W4 bar grating.\u00a0 \u00a0It\u2019s made by taking steel bearing bars placed 1-3\/16\u201d on center and joining them together by welding wire rod cross beams perpendicular to the bearing bars every 4\u201d creating an open grid.\u00a0 The grating typically has either a painted or galvanized finish depending on the application.<\/p>\n

\"Galvanized

Serrated and galvanized open bar grating on a landing bound for the outdoors.<\/p><\/div>\n

 <\/p>\n

Galvanized and serrated open bar grating is an ideal deck solution for outdoor applications.Open bar grating has many advantages as a decking material.\u00a0 It is very strong and durable, and the grated surface provides excellent traction.\u00a0 For particularly slick locations, such as oil factories or outdoors in icy environments, we offer a serrated version for even better grip.\u00a0 As an open decking surface it easily allows water, air, and light to pass through the system.\u00a0 This is why it is a particularly popular decking material for outdoor applications.<\/p>\n

There is one common misconception about the open bar grating that I would like to note though.\u00a0 We are often asked to put open bar grating in sprinkled environments, with the customer thinking that they will not need to add sprinkler lines below the platform.\u00a0 Unfortunately this is not the case.\u00a0 The decking and framing of the mezzanine system occlude the area below enough (even before factoring in the materials on top of the platform) that your fire inspector will still require you to sprinkle below the deck if it is sprinkled above.<\/p>\n

Oddly enough, open bar grating\u2019s strengths are also its weaknesses.\u00a0 As a fabricated steel material, it is significantly more expensive than the resindek.\u00a0 The grated surface makes it extremely difficult to roll pallets and such around on top without adding something like a layer of plywood in order to provide it with a smooth surface to roll across.\u00a0 And as an open, porous material it allows things to flow through it, such as fingers, heels, dropped hardware (i.e. nuts, bolts, screws), or spilled material.<\/p>\n","protected":false},"excerpt":{"rendered":"
