What happens here

The team moves to the final stages of the finishing process. The paint department head demonstrates the use of a Defelsko Positest DFT Coating Thickness Gauge to meticulously measure paint thickness on a newly painted trailer frame, ensuring it meets exact specifications both when wet and after drying. This rigorous auditing guarantees consistent paint quality. Trevor then guides viewers through the assembly line, explaining that 3/4-inch plywood is used for all floors and 3/8-inch plywood for all walls, regardless of the trailer's size. He also points out the custom de-coiling machine, which unwinds large rolls of pre-painted aluminum, cuts them to precise lengths, and prepares them for attachment to the trailer. This innovative system allows Southland to produce trailers of any color on demand, avoiding the inefficiencies of batch processing and offering unparalleled customization.

Goal: Detail the quality assurance process for paint thickness and the flexible system for custom-cutting and applying colored aluminum panels.

Tools and materials

  • Custom De-coiling Machine — Unrolling and cutting pre-painted aluminum sheets to size
  • One-Piece Aluminum Roof — Sealing the top of the trailer
  • Plywood — Interior flooring (3/4 inch) and walls (3/8 inch)
  • Pre-painted Aluminum Coils — Exterior skin of the trailer in various colors

bring static is crazy Tyson have a look at this all right guys this is Tyson he controls this whole department of the shop is that right Ty okay so tell me about this what is it Electro static paint process okay electrostatic paint so what it is is we uh electrically charge the trailer with two grounds in the paint room and when we spray it with the gun it creates a positive charge which wraps around our steel and it's able to get in all those little nooks and crannies that you wouldn't regularly be able to get into which is like an automatic your person spraying by hand so we have a lot of little cracks and crevices that we need to get into and with this process we're able to get right into those spots without having a let's let's break that down though let's break that down you actually stick a clamp you bring this tra these trailers into this booth right here you stick a clamp onto one side of the trailer and a clamp on the other side of the trailer and then that creates a negative ground Y and then as the paint's coming out of the gun it's getting positively charged is that right yeah that's correct so when it comes out of the gun out of the tip there's actually a little wire on the end of the tip of the gun that charges that paint before it comes out of the gun so when it's going through the paint lines and going through the booth nothing's left electrically charged as soon as they pull that trigger and that paint starts coming out of the tip of the gun then it charges it right out of the tip as it goes around the trailer so if I understand this correctly it's like creating a magnetic Bond right so that paint just stick right to it but that'll also go around all of those crevices and get in there so a guy doesn't you don't have to depend on a guy flat painting it that paint's going to automatically go around and grab everywhere that it possibly can't do okay yeah so if we're standing on the outside of the trailer here and I was painting here I wouldn't have to go inside of this trailer to paint it cuz if I'm here the paint is wrapping around it and actually painted back up I want to see the audit process though the audit process I want to see what how you actually audit it I want to see it okay so after we paint our painters will come we'll go down to the finish line here we'll show you one that just came out of the booth okay boy trailer comes out of the booth we'll have our painters come and they have a standard M gauge uh wet mil gauge test but…
