   Metalstone Technologies, Inc. specializes in preventive building maintenance. We are committed to giving you

the best quality care, craftsmanship and service in maintaining your metal, stone, ceramic and wood surfaces.

   Metalstone Technologies, Inc. wants to restore and maintain all of your buildings’ metal. The entrance doors and revolvers, exterior window frames and mullions, elevators, directories, stanchions, fire department standpipes, thresholds, bathroom partitions, cabinets and signs are just some of the items that we can protect from   oxidation, corrosion and depreciation.

   There are many types of metals used in the building industry. Bronze, brass, copper, stainless steel and aluminum are the most popular.

 

Bronze is a hard yellowish-brown copper and tin alloy (substance containing two or more metals) developed around 3500 BC. Bronze is stronger and harder than any common metal alloy except steel. It does not easily break under stress, is corrosion resistant, and is easy to form into finished shapes by molding, casting or machining. As bronze weathers, a brown or green film forms on the surface inhibiting corrosion.  Many bronze statues erected hundreds of years ago now show little signs of corrosion.

 

Brass is a hard yellow shiny metal that is an alloy of copper and zinc, frequently with the addition of other metallic elements to impart specific properties. Brass is also much harder than copper and is quite versatile lending itself to everything from musical instruments to elevators doors.

 

Copper is a brownish-red metallic element that can be easily shaped or bent without breaking and is a great conductor of electricity. Copper was known to prehistoric people and was probably the first metal from which useful articles were made. Copper objects have been found among  the remains of many ancient civilizations, including those of Egypt, Asia, China and southeastern Europe.

 

Stainless Steel is a corrosion-resistant steel containing at least 12 percent chromium. Stainless steels are used in petroleum refineries and chemical plants, surgical instruments, jet planes, and space capsules. It is also used to patch or replace broken bones because the steel can withstand the action of body fluids. In kitchens and in plants where food is prepared, handling equipment is often made of stainless steel because it does not taint the food and can be easily cleaned.

 

Aluminum is a silvery white, light metallic element that can be easily shaped and bent without breaking. It is the most abundant metallic element in the Earths’ crust  weighing less than one-third as much as steel. The only lighter metals are lithium, beryllium, and magnesium. It’s high strength-to-weight ratio makes aluminum useful in the construction of aircraft, trains, and cars, in which energy conservation is important. Architecturally, it is becoming more popular because of it’s low cost, resistance to corrosion, and excellent insulation properties. Aluminum can also be anodized (coated with a protective or decorative oxide) to give it many colors.
