Design & Specifications
Our team makes sure every step of fabrication and design yields a quality product that lasts for decades.
We will work with you from the start of your bid process to ensure that we communicate what is needed for proper fabrication for galvanizing. I.E. venting and draining of zinc, methods to minimize warpage & distortion, even stitch weld gap spacing to get the best quality possible for your galvanized project.
At any point, we encourage you to reach out to us so we can address any scenario we may encounter upfront. Keep in mind that we will stand by the coating you receive and take our commitments seriously.
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
- D 6386
The Finishing Process: Cleaning to allow for the intended use of the product
- Handrail smoothing
- Grind wire marks
- Free moving parts frozen from 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 ground down to prevent injury during install
- Threaded parts: masking & cleaning
- Special packaging requests
- Assembly requests
Tell us when you need a higher quality finish (our default is Finish Grade A) prior to sending so that we can work with our foremen to give you what you are looking for.
Keep in mind that first and foremost galvanizing is corrosion protection intended to defend against the unruly elements of nature. Due to the varying nature of steel chemistry, some appearances that could be the perceived galvanizing look are at times unattainable.
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)
