16 oz. Vinyl
EACH TENTS INCLUDE:
16 oz. Tent top, 14 oz. white sidewall (heavy duty bags for top & sidewall), galvanized steel center pole(s) & wall poles, ropes, stakes, instructions, fire marshal certificate & repair materials. 50′, 60′, 70′, 80′ & 100′ tents will have aluminum center pole(s) & 60′, 70′, 80′ & 100′ will have galvanized steel quarter poles. (The 30′, 40′, 50′, 60′, 70′, 80′ & 100′ tents receive 1 trucker’s ratchet)
Superior materials are used throughout: For 18 oz premium round & oval tents. A unique vinyl laminate* made to our specifications makes our tent a lot better. The fabric (scrim) in the laminate that provides much of the extraordinary strength of our tent, is a polyester (Dacron) rip-stop cords every inch, 9 each way. (This is dramatically stronger than industry standard which is just 1000 denier.)
The vinyl contains extra U. V. protection, including plenty of titanium dioxide, which enables this unique vinyl to exceed all others in sun resistance and length of life. The vinyl has all the finest color-fast pigmentation it can absorb. All our colors are guaranteed to last for years without fading. (These pigments cost more, but they’re worth it.)
Our extra thick vinyl, 16+ ounces per yard, substantially increases sun resistance, abrasion resistance, and smoothness. It incidentally provides a firmer, more stable surface into which to vulcanize our permanent weather-proofing materials over every seam. (Again, this is much stronger than industry standard of 13-14 ounces per yard.)
An abundance of polyester, U. S. manufactured, is used in our seat belts on every seam, and in our thick (#207) thread-as well as in the inner “scrim” of our vinyl. Even our ropes are wound with polyester for guaranteed sun resistance and abundant strength. Polyester is about twice as strong as cotton, and being an oil based product, like vinyl, it is all but impervious to mildew or rot of any kind.
Polyester does not react very much to extremes of temperature or humidity. Its size, shape and strength are stable, unlike cotton, hemp, or even nylon. All the steel-to-steel connections, including the special twin bail-ring, are hot-dip galvanized, like coated nails, for 30 year rust resistance!
The tent top and side-wall are composed of nothing but the finest vinyl, domestic polyester, and galvanized steel hardware. What this means is that your tent is not only as strong as modern science and modern technology can make it, but it will not grow slack when cooling, soaking rains come, and then sag into “water bags” and come down. By the same token, it will not stretch too tightly (like nylon will) in the sun. It will not change noticeably from one month to the next. (See “Product description for premium 18 oz. tents”.)
Superior design and detail work may be found throughout. The unique bail-ring (pronounced “bell-ring”) is suited to either “push-pole” or pulley raisings with never a chance that the center pole could damage the tent through abrasion.
Unique hook and ring connectors at tent top, eave, and in 61′ and larger tents, at the quarter-band, help the tent easily endure the enormous forces in storms that can destroy weaker tents.
Our triple stitch seams with #207 polyester thread are about four times stronger than a normal double stitch with #138 thread. And again, polyester is about twice as strong as cotton. This is the miracle of modern materials. This translates into a product you can depend upon.
The quarter-pole positions: In 61′ and wider tents, the quarter poles carry most of the wind load as well as the weight of the tent itself. We therefore make these points particulary tough. The quarter poles are naturally positioned where seams cross with their 5700 pounds-strong seat belts.
To that we add:
An extra seat belt for 4 feet on both seams where they cross. A small and then a larger kite-shaped vinyl over the area. Three layers of our powerful vinyl laminate, adding over 300 lbs. per inch, each. Quarter pole domes on large tents have tough, aluminum “heads” of 28 square inches (a 6″ disk) built right into the tent at every 1/4 pole position. They articulate, staying flush with the tent at all times.
These areas therefore become very reliable “strong points” that can easily carry the weight of virtually any storm. One tent-100’x148′-took 14″ of wet snow in Philadelphia. That surprised even us. With slanted quarter poles, the wind pressure simply passes through the quarter poles harmlessly to the ground. With vertical quarter poles that some medium sized tents may use, about one-half of the load passes into the ground, the rest down to the stakes.
Double belting: To add strength and safety to every area susceptible to stress, we use two seat belts in the following areas: All edges including the entire perimeter. Quarter-pole positions as indicated above.
The seam at each “end” of every tent. This means that if you elect to add one or more “middles” to lengthen your tent you can pull the tent from each end very hard without special guy lines. (The strength of this one seam is over 13,000 lbs!)
The center-band of every middle (from pole to pole) is a special belt 3″ wide and some 18,000 lbs. in breaking strength. The 10″ rain-flap over the laced edges of the tent section is closed 100% effectively with industrial vel-cro, and it looks great. The valance of each section also connects firmly to other sections with vel-cro. And even in winds of 100 mph, tests show they always stay right in place. Movement simply causes vel-cro to tighten up.
Our deluxe side-wall (curtain) is special in four ways: 11⁄2″ belt around edge. Stainless steel snap hooks and zinc grommets that will never rust. Bi-fold corners, 4 layers thick, so any one edge of the sidewall can absorb up to 1000 lbs. of stress if need be. The vinyl scrim of the sidewall is as strong as any tent top material we’ve seen except our own.
A score of significant detail items that cannot be enumerated here, but can be seen, used and appreciated. Continuous research and development, evaluation and testing, insures that Miami Missionary Tent Company will continue to advance the state of the art. Two layers of vinyl bonded permanently to either side of a polyester fabric.
