Tennessee Blast & Coat in Chattanooga: Industrial Finishing for Automotive and Metal Work

Tennessee Blast & Coat is a powder coating and abrasive blasting facility in the Chattanooga area that handles industrial metal finishing for automotive restoration, fabrication shops, and equipment manufacturers. The operation combines surface preparation (abrasive blasting) with powder coating application, letting jobs move from bare metal to finished coat in one location. This integration matters because outsourcing blasting and coating separately adds time, handling risk, and coordination overhead that shops in the region typically avoid when possible.

What Tennessee Blast & Coat Actually Does

The shop performs two core functions. Abrasive blasting removes rust, mill scale, old paint, and surface contaminants using equipment that propels fine media (sand, glass bead, or steel shot, depending on the substrate and finish requirement) at high velocity. Powder coating applies a dry, electrostatically charged polymer powder to the cleaned substrate and then cures it in an oven, creating a durable, uniform finish without the drips, sags, or solvents of traditional liquid paint.

The facility handles custom colors and clear coats. Typical work includes automotive frames, suspension components, machinery parts, decorative metal fabrications, and structural steel. Jobs range from single motorcycle frames to production runs for regional fabrication shops. The operation is not equipped for large-scale commercial architectural coatings (building facades, structural beams for construction) but excels at precision custom work where finish quality and color match are non-negotiable.

Services and Pricing

Abrasive blasting rates vary by substrate and desired finish. Steel and cast iron run $25 to $45 per hour of labor, with additional costs for media if the customer does not supply it. Aluminum and non-ferrous metals cost more, typically $35 to $55 per hour, because they require softer media (glass bead or plastic) to avoid surface damage. Most jobs include both labor and material in an estimate.

Powder coating pricing follows a per-piece or per-square-foot model. Small automotive parts (control arms, brackets, wheels) range from $75 to $200 per piece depending on surface area and complexity of masking. Larger assemblies (full frames, fuel tanks, engine blocks) cost $300 to $800 or more. Custom colors carry a setup fee of $50 to $100 per unique color; standard colors (black, white, gloss red, clear) do not. Metallic or textured finishes add 15 to 25 percent to the base rate.

Turnaround depends on the queue. Simple jobs with standard colors typically ship within 5 to 7 business days. Multi-part orders or custom blends may take 10 to 14 days. Rush service is available but requires advance notice and costs 20 to 30 percent more. Call to confirm current rates and timeline, as material costs fluctuate seasonally.

How It Compares to Other Chattanooga Powder Coating Options

Chattanooga has several powder coating providers. Most are single-process shops: they either blast or coat but not both. Tennessee Blast & Coat's in-house blasting eliminates the hand-off delay and risk of contamination between vendors. A competing shop in the area offers coating only and requires customers to bring pre-blasted parts, which adds a sourcing step. Another local provider does both but operates with longer lead times (14 to 21 days standard) and higher minimums on custom colors.

Tennessee Blast & Coat is the better choice if you need coordinated preparation and coating with faster turnaround and no minimum order requirement. Choose a coating-only shop if you already have a blasting vendor and want price competition on the final step. Choose the higher-volume vendor if you run monthly production batches of 50+ parts and can wait 2 to 3 weeks for a job.

Who It Suits and Who It Does Not

This shop fits automotive restorers, custom fabricators, local equipment manufacturers, and hobby builders who need reliable quality and reasonable turnaround. It also serves shops that do their own fabrication and need finishing as a subcontract step. The facility is not ideal for one-off decorative items where the customer has never specified a powder coat before and needs significant guidance on color selection, finish type, or prep requirements, though the staff can advise.

It is not a high-volume production coater. If you need 10,000 brackets powder coated annually, you will find lower per-unit rates elsewhere. It is also not a liquid-paint alternative for applications that require fast air-dry (emergency repairs in the field) or for substrates that cannot withstand oven cure temperatures.

What the First Visit Involves

Call or email with photos and dimensions of the part. Tennessee Blast & Coat will quote the job over the phone or via email if details are clear. If you are unsure whether powder coating is the right finish or need blasting medium recommendations, bring a sample part to the shop. The staff can evaluate prep requirements and suggest media options. No appointment is required for a simple quote or consultation, though calling ahead prevents a wasted trip if the owner is offsite.

Once a job is approved, drop off parts during business hours or arrange pickup for large items. You will receive a written estimate confirming the blasting media, powder color, finish type, and completion date. The shop does not require a deposit for jobs under $500; larger orders typically require 50 percent upfront.

Hours, Parking, and Logistics

Tennessee Blast & Coat operates Monday through Friday, 8:00 a.m. to 5:00 p.m., with Saturday hours by appointment. The facility is located off Rossville Boulevard in an industrial area with dedicated parking for customer vehicles. The space has a covered drop-off bay, so you can unload parts without exposing them to the weather.

The shop does not offer shipping, but UPS and FedEx can pick up completed jobs directly from the facility. For large items or production runs, discuss delivery logistics when you place the order.

Tennessee Blast & Coat fills a practical gap in Chattanooga's finishing market: it combines two time-consuming steps without the friction of juggling two vendors, and it prices competitively enough for restorers and small manufacturers to use it as their default instead of an occasional vendor.
