TEMCOR - A Leader in Aluminum Space Structures

Temcor, founded in 1964, designs, manufactures and erects architectural and environmental prefabricated structures and enclosures. These are primarily clear-span domes and related space frames fabricated mostly from aluminum. Temcor structures are used for covering tankage of all types as well as architectural applications such as arenas, gymnasiums, theaters and auditoriums.

Superior Engineering & Service

More than forty years of pioneering design and engineering is built into every Temcor Product. More than 7,000 Temcor aluminum domes have been installed throughout the world. Most importantly, our prefabricated structures and metal buildings have withstood the test of time even in the harshest environments. Behind these structures is a remarkable company.

Temcor built the first aluminum dome for a water storage tank in 1968, for a wastewater tank in 1969, for a petroleum tank in 1977 and the world's largest free standing aluminum dome measuring 136 meters in diameter in 2006, and the second largest dome measuring 127 meters in diameter in 1982. All of these are still in service, as are other Temcor domes withstanding the heat of a Middle Eastern desert, typhoon winds of 300 kilometers per hour on a Pacific Island and uneven snow loads of 1,500 kilograms per square meter in the Antarctic. Research and Development receives major emphasis at Temcor.

Temcor products are precision fabricated to aircraft tolerances. Aluminum has its advantages! Time-tested maintenance-free, corrosion-resistant materials are used, such as proven aluminum alloys, stainless steel fasteners and silicone rubber sealants and gaskets.

Aluminum Advantages

Temcor Aluminum Geodesic Domes, covers and structures feature all-aluminum construction. Temcor products are lightweight, corrosion resistant, and virtually maintenance-free, which translates to longer life and lower costs. They don't rust like steel, they don't degrade with ultraviolet light like fiberglass, and they don't spall like concrete. And their strength and versatility are unmatched.

Aluminum is vapor-compatible with everything from sewage to most process chemicals and treatment processes. For example, hydrogen sulfides and mercaptans don't attack aluminum. In short, its corrosion resistance makes it the ideal material for most industrial applications. That's why Temcor specializes in all-aluminum structures.

Temcor Construction Methods

The Tower Erection construction process consists of a dome being erected from the center outward to the perimeter using a center erection tower. Workers assemble the frame on the ground, lifting the dome up as each strut ring is completed. On average, a Temcor Aluminum Dome is assembled using one-third the man hours required for conventional construction.

The Crane Erection process consists of a dome being erected on the ground and then lifted into place with a crane. This process can save valuable construction time since the dome and tank or support walls can be built simultaneously. A dome for the water or wastewater industry can be installed without taking the tank out of service.

Where space is limited, the In-Place Erection process consists of a dome being built directly on a tank or building wall. The dome is assembled from the outside toward the center.

Big Savings

The initial cost of alternate structures plus the required materials and structural maintenance expense typically exceed that of a Temcor structure. In total, Temcor's all-aluminum construction offers cost savings versus other materials over the life of the structure.

Temcor Aluminum Domes

Efficient in design, distinctive in appearance, unsurpassed in quality and value - Temcor Aluminum Domes are as beautiful as they are efficient and enduring.

Design Flexibility

The Temcor Aluminum Dome is a unique and patented triangulated space truss skinned with aluminum panels secured by a patented Temcor batten closure system.

With an ability to cover spans from 40 to more than 1000 feet, Temcor Aluminum Domes are specified for churches, arenas, planetariums and observatories… wherever clear-span roof systems are needed. Aluminum integrated structural frames are permanent and lightweight and optional panel systems offer eye-dazzling options.

Superior Design and Lower Cost

The dome's superior structural design gives it many advantages. Using proprietary variations of geodesic geometry, Temcor Aluminum Domes are noted for their ability to meet exacting live load requirements by providing greater stiffness and strength, pound-for-pound, than any other dome geometry system.

Temcor domes have been designed for snow loads of up to 165 pounds per square foot and windloads of up to 150 mph. And, Temcor's panel design is specifically engineered to support loads of up to 500 pounds on any one square foot.

And the energy efficiency of Temcor Aluminum Domes translates to reduced operating expenses. Since they're made of aluminum, they have the inherent advantage of high heat reflectivity and low emissivity. That means lower heating and cooling costs.

Save on maintenance dollars too. The permanent aluminum exterior never rusts, rots, spalls, or solar degrades. And because Temcor Aluminum Domes use less material and labor than conventional constructions, overall costs are lower and construction time is faster. The built-in advantages of aluminum and lifetime beauty of a Temcor Aluminum Dome will be appreciated for years to come.

Protecting Resources and the Environment

Water, wastewater plants and storage facilities are increasingly turning to the Temcor Aluminum advantage. In addition to low maintenance, low cost and low profile advantages, Temcor Aluminum Domes and reservoir covers are versatile enough to permit a wide range of accessories important to the water, reservoir and wastewater industry.

And, it's the dome's design that gives it many of its advantages. Using proprietary variations of geodesic geometry, Temcor Aluminum Domes and tank covers are noted for their ability to meet exacting live load requirements by providing greater stiffness and strength, pound-for-pound, than any other dome geometry system.

Temcor domes have been designed for snow loads up to 165 pounds per square foot and windloads of up to 150mph. And Temcor's panel design is specifically engineered to support loads of up to 500 pounds on any one square foot. Yet, Temcor domes weigh a mere five percent of conventional concrete equivalents.

Temcor domes promote process efficiency in cold climates, and they can't be beat for containment of odors and vapors. In fact, their low profile reduces vapor space. And their all-aluminum construction is completely resistant to hydrogen sulfide, chlorine and other corrosive vapors found in water and wastewater treatment plants.

Bulk Storage

Temcor Aluminum Domes: Strong and Versatile

Temcor's unique space truss design and highly engineered components combine to make Temcor Aluminum Domes the ideal solution for challenging environmental enclosure and bulk storage problems. Whether it's keeping the elements out or getting the largest amount of bulk in the smallest amount of space, the Temcor solution has proven itself time and again.

Consider the advantages of aluminum in bulk storage and material handling. Temcor domes offer the ideal span-to-rise ratio in standard and custom designed configurations for any clearance requirement. And in applications requiring vertical headroom near the dome's edge, Temcor Aluminum Domes can be erected on vertical steel wall frames, providing maximum unhampered space for material handling.

Temcor Aluminum Domes: Light and Strong

Still another advantage of a Temcor dome is its light weight. That means reduced foundation costs. But its weight belies its strength. When applications require, Temcor Aluminum Domes can even be designed to support heavy processing equipment. From the blazing Mojave Desert to the gale force winds and snow of the Antarctic, Temcor Aluminum Domes have repeatedly proven their strength, durability and flexibility.

Petroleum/Petrochemical

Temcor Aluminum Domes have Revolutionized Tank Covers

Temcor Aluminum Domes are noncombustible structures that remain unaffected by the corrosive effects of petroleum vapors. Furthermore, their clear-span design means reduced vapor loss, since internal floating roofs can be operated without interior support column penetrations.

Rainwater infiltration and most wind-induced vapor losses are eliminated when external floaters are dome covered.

Superior Strength & Safety

Tanks can remain in service while the tank roof is built, since no hot work is required during the process. And, because Temcor aluminum domes are prefabricated, field erection time and labor costs are minimal. For instance, three people have erected a 100-foot dome in just five days. A typical Temcor dome weighs just 2.5 pounds per square foot, just one-fifth the weight of a comparable steel roof.

Temcor Aluminum Domes are not only water tight, but they can be built vapor tight where vapor recovery or other operational needs require.
