What We Galvanize
Emerald specializes in galvanizing smaller parts, hardware, and fabrications which are usually difficult and often not economical to galvanize in a large kettle. We also galvanize light to medium weight fabrications and anchors, and anchor chain. We charge $1.25/Lb for anchors & chain. Feel free to use the calculation chart below to figure out how much it may cost for your order.
Most small parts (including all small threaded parts) are run in our perforated buckets and then are centrifuged immediately after hot dip galvanizing. The centrifuge rapidly spins the buckets to remove excess zinc. The centrifuge process keeps sharp edges from forming on fabrications and keeps bolt threads clean. This saves you labor charges to clean up parts.
Larger fabrications are usually wired or chained up before lowering them into the kettle for galvanizing. Our overhead cranes slowly lift these fabrications out of the molten zinc at an angle so that excess zinc runs off. Our galvanizers are experts.
Typical types of producst we galvanize include:
The minimum diameter for galvanizing fasteners is 3/8” and the minimum size for galvanizing wood screws is #18. Bolts and chains up to a Rockwell hardness grade of 40 are usually acceptable to galvanize. Call us for our advice on other grades.
Calculate your own estimate on chain:
We only galvanize up to 300 ft. at one time, if your chain is 3/8" or less. Chain over 3/8" needs to be cut in half so that we put less chain into our centrifuge at one time. The less chain we put through the process, the higher the quality. We can cut your chain for you, and refer you to a steel shop that can re-link it for you with a galvanized link. This does not cost a lot, and does not affect the strength of your chain. View the chart below which is a Sample customer estimate. You can also download our excel file to type in your own chain length - below the picture is a link.
How much time does it take to galvanize my anchor or chain? Approximately 2 weeks. We call you when your order is done. You can pay when you pick up with cash, check, or credit card. If you have not received a phone call, that means your order is not done.
Does all chain need sandblasting? No. Light surface rust will come off during galvanizing preparation. Only deeply pitted rust, paint, lacquer, and markers need to be fully removed using sandblasting prior to hot dip galvanizing.
How much does sandblasting cost? Sandblasting charges cannot be estimated because the person doing the work does not know before he begins how long it will take. However, it is billed in 15 minute increments at $150.00 per hour. We keep the costs as low as possible for you.
