This is my first 4spec post so I hope I am putting this in the right location. We are designing an oxygen tank screen for a local hospital. Three sides are masonry. The front would be a nonflammable sight proof fence with a 6’-0” wide x 12’-0” tall cantilever gate to allow access. Chain link is not allowed by the local municipality. Does anyone have any recommendations for a fencing manufacturer that could produce that?
Any suggestions would be greatly appreciated. |

Go to a local architectural metalwork fabricator to design and fabricate a steel tube frame gate with infill panels, such as perforated steel sheet, corrugated metal panels, architectural mesh, etc.

I cut my teeth in the commercial fence industry, and my ideas may be a little outdated. But here goes:
This is not something you will be able to find in a catalogue - at least not one I know of.
A local fence company could easily make the welded pipe framework. Look for the best local commercial fence company you can find. Visit its facility. The company should have experience in fabricating and installing cantilever gates.
If you cannot find a fence company per se, an ornamental iron fabricator can do the job, but probably at a higher cost.
The non-flammable sight-proof panel infill could be achieved with sheet metal or metal decking. Corrugated metal will allow you to keep the weight under control while retaining some dimensional strength. Depending on your budget, you could also consider perforated or expanded metals, which are easy to find online (Moz Metals, McNichols, or a local ornamental iron fabricator). Remember, keeping the cumulative weight under control is important with these projects for a few reasons.
A shop-applied finish applied skillfully can make the gate inoffensive looking if not aesthetically pleasing.
The cantilever rollers and other fittings are available from the same commercial fence companies who make the gates, as well as a gate operator, if needed. Because this is a large gate (12' high), you probably should have an operator for safety.
To be sure you have sufficient room for the cantilever to operate, review the International Fence Industry Association's standards. It is a good reference.
I hope this helps. Let us know. |

Jeff,
I have specified doors from Crown Industrial Supply at www.crown-industrial.com for similar openings. Door style #974-2. Doors are single panel sliding to one side of the opening in a CMU wall. Send me an e-mail to wayne.yancey@callison.com for sample details of our installations.

If your firm has a MasterSpec subscription, Section 323119 "Decorative Metal Fences & Gates" might be a good source of information for assemblies of the type you describe, in addition to a listing of fence & gate manufacturers that might be able to produce it. Gate operators are also covered in this section, if needed. |

Thanks, I have been considering the local fence company option. That would be the simplest option. Competitive bidding is where I run into problems. Ametco could produce a system but I am pretty confident they will be over budget. I will put a call into a local fence company tomorrow. Thank you! I appreciate the info from you all!

Yes, we have BSD SpecLink I will check there also.

It would be important to know if the fence is intended to enclose the tanks or to actually contain the tanks. A tank can become a missile and they typically have to be securely enclosed. If the tanks are chained (or contained in some other fashion) then the fence could easily be fabbed by a local fence company.
If the fence has to contain the tanks then you may have a completely different set of criteria to deal with. |

The enclosure is decorative. There is a footing under the tank that it will be bolted to. It’s a big tank so if it comes unglued, “Katie bar the door”! I will be glad I am on the south side of Saint Louis.

Hi Jeff,
Sorry I missed this thread earlier - nice to see you on 4 specs, and welcome...
Missouri Ornamental Iron on Olive in University City used to be a go to resource for me – I believe they are still around. Collins and Herman may be another source, but my impression is that they typically do bigger projects.
