MAX TwinTier: A New Era in Rebar Tying

Rebar, or reinforcing bar, is the backbone of concrete work. While concrete is strong in some ways (compression strength), it’s weak in others (tensile strength). In simpler terms, it means concrete can stand to be pushed more than it can to be pulled.

That’s where steel rebar comes in. Steel has a high tensile strength and is added to concrete structures to give the needed strength to support buildings, roads, retaining walls and the like. Before concrete is poured and set, steelworkers lay the rebar according to specified building and construction codes.

Rebar comes in a range of coatings and gauges, depending upon application. The rods must be connected by corresponding ties, a tedious yet important process, to keep the rebar from moving while the concrete is poured.

Max Rebar Tool and Rodbuster at Work

From Manual to Power Tiers

To save costs, materials and manpower, it was only a matter of time before a powered rebar tying tool was created. Tying rebar is tough on the body, mainly the wrist, shoulder and back. For a rodman, or rodbuster, repeatedly twisting metal wire can be permanently damaging over the long-term. A NIOSH (National Institute of Occupational Safety and Health) study in 2005 revealed the potential health hazards and suggestions for making a safer work environment. If a worker is tying rebar for more than an hour per day, NIOSH recommends providing a cordless tying tool and a tying tool extension arm.

Purchasing a cordless rebar tier is truly an investment. Looking for a strong lithium ion battery that holds a decent charge is key, as is a balanced tool that prevents fatigue and potential injury. Before you buy, make sure the tier is not only fast, but makes a strong, secure tie.

The MAX Effect

Without a doubt, one of the most familiar names in rebar tying tools is MAX USA Corp. They’ve been perfecting power tools for more than 20 years. MAX created the first battery-powered rebar tying tool, the RB262 (which used a nickel cadmium battery) in 1993. In 1998, power tiers became available to the American market, and the rest was history.

Currently, the cordless MAX RB398 is among the most popular tiers at Nail Gun Depot. Weighing a mere 5 lbs. and delivering more than 2,500 ties per battery charge—that’s 5x faster than manual tying—the RB398 can hold its own. Plus, it eliminates the need to disperse and cut rebar wire, saving on materials waste.

But just when you thought they were done, MAX once again improves on their already bullet proof design.

Dual Wire, Dual Savings

New to the market for 2018, the MAX RB441T TwinTier offers an incredible output of 4,000 ties per battery charge. That’s a 200% increase from the previous models. The TwinTier also creates a highly secure connection thanks to a dual-wire feeding system, which dispenses two 19-gauge wires at once to form a tie. The tie is 50% tighter to boot.

Like most rebar tiers, the RB441T comes in three tie wire options: regular or annealed steel, the most commonly used; galvanized with a zinc coating, which adds 40 times more corrosion resistance and is used for moist or marine environments; and polyester-coated wire, which is abrasion-resistant and at least 70 times more corrosion-resistant than annealed steel. The tie wire rolls are changed out in about half a second, an improvement compared to previous models.

Due to the TwinTier’s patent-pending wire bending mechanism, the tie it creates has a 50% shorter height than the projecting “rabbit ears” produced by older cordless models. What does this mean to the concrete construction job overall? It means less concrete is needed to cover the tie, which further saves on materials.

Not only does the rebar tying tool save on materials and time, but labor. Fewer tiers are required per job, and an ironworker doesn't need the advanced tying skills and speed of years past. The tedious, wrist-twisting work is done for you - no strings attached.
