From Idea to Jobsite: Inside EZG’s R&D Process

In the masonry industry, equipment is rarely developed in isolation. The most effective tools are shaped by real jobsite challenges and refined through contractor feedback. At EZG Manufacturing, research and development is a hands-on, iterative process that moves from concept to production with input at every stage.

Where It Starts: An Idea
Every product begins with a need identified either internally or by contractors in the field. These ideas often stem from inefficiencies, safety concerns or opportunities to improve workflow. EZG works closely with masonry professionals to understand how equipment performs under real conditions, ensuring early concepts are grounded in practical use.

“The best ideas usually come from the field,” said Steve Wheeler. “Contractors are the ones using this equipment every day, so their input drives how we approach new designs.”

From Concept Drawings to Design
Once an idea is defined, it moves into concept development. Initial drawings are created and reviewed, often going through multiple revisions before a direction is finalized. At this stage, the focus is on layout, functionality and how the equipment will integrate into existing workflows. Small changes here can have a significant impact on long-term usability and durability.

Building the First Model
After design refinement, fabrication of a working prototype begins. This stage introduces real-world considerations not always evident on paper. Material selection, component placement and structural integrity are evaluated as the equipment takes form. Adjustments are common as performance and balance are tested during the build.

“There are always changes once you start building,” Wheeler said. “You learn quickly what works and what needs to be improved before it ever reaches a jobsite.”

Field Testing and Feedback
Prototypes are then placed with contractors for testing across multiple job sites. This step is critical for evaluating performance under varying conditions, including different materials, crew sizes and environments. Feedback gathered during this phase helps identify revisions related to efficiency, safety and durability.

Testing across multiple sites ensures the equipment performs consistently rather than being optimized for a single application.

Refinement and Production
Following field testing, final adjustments are made before the product moves into production. The focus shifts to reliability, repeatability and ease of use. Only after the equipment meets performance expectations in real-world conditions does it move to market.

This process is supported by EZG’s in-house manufacturing capabilities. The company operates a 185,000-square-foot facility designed for full-scale production and holds ISO 9001:2015 certification. That vertical integration allows design, fabrication and quality control to remain closely aligned throughout development.

New Product Spotlight: Buzz Hog Radial Arm Saw
The development of the Buzz Hog radial arm masonry saw reflects this process. Designed to address safety and control challenges associated with traditional cutting methods, the saw brings the blade to a stationary block rather than requiring material to be pushed into the blade.

The unit features a solid table for straight and angled cuts, an enclosed blade system and an integrated water filtration design to manage dust and slurry. A handle-activated blade brake enhances operator control, while the saw’s mass helps reduce vibration for more consistent cuts.

“This was a product that went through multiple iterations,” Wheeler said. “We wanted to improve safety while also giving contractors better control and a cleaner cutting process.”

Closing the Loop
For EZG, research and development is an ongoing cycle. Feedback from completed products often informs the next generation of equipment, creating a continuous connection between the shop and the jobsite.

As masonry work continues to evolve, that contractor-driven approach remains central to developing equipment that performs where it matters most.
