Design & Specifications
OUR Specifications
Knowledge is power. This statement has never been truer than when it comes to galvanizing. Our goal is to establish transparency and direction from the very beginning so that the end product adheres to the required specifications for your unique project. By having these important conversations about the material, intended use, and specs we can make the best decision on how to process your material to achieve the optimal galvanizing coating. The main factors to consider during the design of the project to be galvanized include-
- Venting and draining of molten zinc during dip
- Methods to minimize warpage & distortion
- Thermal expansion consideration
- Stich weld gap spacing
- Threaded parts
- Masking instructions
- Accurate measurements
- Drawings and visuals
- Intended use
The more information you give us, the better we can serve you. Communication is key to maximizing quality while closing any margin of error.

HOT DIP SPECIFICATIONS
We meet or exceed the following ASTM specifications:
- A 123/123M
- A 153/153M
- A 143
- A 384
- A 385
- A 767
- A 780

The Finishing Process: Cleaning to allow for the intended use of the product
- Handrail smoothing
- Grind wire marks
- Free moving parts that become frozen during galvanizing
- Grind base plates
- Clean tube splice insertion points (test splices are a good thought to send so we can achieve this for you)
- Grind zinc drips down to prevent injury during installation
- Threaded parts: masking & cleaning
- Special packaging requests
- Assembly requests
Please note that due to the varying nature of steel chemistry, some appearances are at times unattainable. When we discuss your projects, we can tell you what to expect.
Proper Drainage
For effective galvanizing, cleaning solutions and molten zinc must flow into, over, through and out of the fabricated article without undue resistance. Failure to allow this can create complications for the galvanizer and the customer.
Improper drainage design leads to poor appearance, bare spots, and excessive buildup of zinc. All of these are unnecessary and costly. Communication throughout the project is key.
Where gusset plates are used, generously cropped corners provide for free drainage. When cropping gusset plates is not possible, holes at least ½-inch (13 mm) in diameter must be placed in the plates as close to the corners as possible (see Figure 7).
To ensure unimpeded flow of solutions, all stiffeners, gussets, and bracing should be cropped at least ¾-inch (19 mm) (see Figure 8).
Provide holes at least ½-inch (13 mm) in diameter that can be placed in the web within ¼-inch (6 mm) of the end plate. To facilitate drainage, end plates should have holes placed as close to interior corners as possible. (see Figure 9)
