Steam curing equipment, system engineering

The manufacturer’s signature equipment for precast, prestressed, pipe, masonry and tile curing, generates large volumes of controllable, low-cost steam. Operating at half the cost of traditional boilers, engineers note, CurePak can show return on investment in two years or less. Its capacity to produce steam instantly and initiate combustion prior to water contacting hot air equates to nearly 100 percent thermal efficiency and carbon monoxide risk reduction. CurePak also fits precast operations with flexible curing parameters, especially those requiring both intermittent and continuous steam flows.

Speedy masonry saw integrates dust collection

Manufacturer presents the iQMS362 as durable, portable and built to tackle any jobsite. It is equipped with the model-specific 16.5-in. Q-Drive blade, capable of 5.5-in. deep cuts at full 24-in. lengths, and equal to masonry materials in a wide range of shapes, sizes, weights and densities—from soft, manufactured stone to granite or high strength pavers.

Galvanized rebar

Company presents GalvaBar as continuously galvanized rebar with proven protection and high formability. It can be fabricated after the galvanizing process without cracking, peeling or flaking. The process coats the steel with minimal exposure time to the molten zinc before cooling. That allows all grades of reinforcement, normal- to high-strength, to be galvanized with no risk of embrittlement.

Stainless steel rebar

High performance reinforcement is used to control the damaging effects of corrosive environments due to chlorides from deicing compounds, marine spray or contamination and spillage from chemical processing in mining, petrochemical or other industrial environments. Company cites a growing trend among state, provincial and federal transportation engineers to specify stainless as it represents the most economically viable corrosion resistant reinforcing steel for chloride attack-prone concrete. Once a structure is built with stainless steel reinforcement, owners and operator stand to see a dramatic reduction in repairs over the service life cycle. Company ships fabricated rebar and reinforcing mats throughout the U.S. and Canada. — Salit Specialty Rebar, Buffalo, N.Y., 716/299-1990,
