From raw fabrication to finished product — under one roof. Lasertech's in-house powder coating eliminates outsourcing delays, adds a durable protective finish, and delivers your parts ready for assembly or shipment. Custom RAL colors, multiple gloss levels, and a wide range of textures.
Lasertech is a complete fabrication-to-finish operation. Parts cut, formed, welded, and powder coated without ever leaving the building — no transportation, no vendor scheduling, no quality gaps between steps.
For customers, this means one point of contact, shorter lead times, and consistent quality across every stage of production — from raw sheet to coated, assembled, ready-to-ship product.
Parts move from fabrication to coating in the same facility — no transport time, no vendor scheduling queue. Powder coating adds days, not weeks, to your overall lead time.
Surface prep, application, and cure are all monitored by the same team that fabricated the parts. Any issues identified during coating are caught and resolved before delivery — not after.
Quote, fabrication, welding, and powder coating — one shop, one contact, one invoice. Eliminates the coordination effort of managing separate fabrication and coating vendors.
The coating team understands sheet metal — masking requirements, hardware locations, and critical dimensions are communicated directly from fabrication to coating without ambiguity or translation errors.
Lasertech also performs assembly — hardware insertion, sub-assembly, kitting, and final packaging. Powder coated parts can move directly to assembly within the same building, further reducing handling and lead time.
Powder coating is a four-stage process — every stage matters. Proper surface preparation determines adhesion. Correct electrostatic application determines coverage. Controlled curing determines hardness and durability.
All parts are cleaned and degreased to remove oils, cutting fluid, and mill scale. Steel parts receive chemical pretreatment — iron phosphate or zirconium conversion coating — to improve adhesion and corrosion resistance. Abrasive blasting is used for heavily oxidized or scaled parts. This stage determines the long-term adhesion and durability of the final finish.
Threaded holes, critical mating surfaces, electrical contact areas, and other features that must remain uncoated are masked before application. Masking plugs, caps, and tape are applied precisely to keep powder off specified areas. Hardware that would be damaged by cure temperatures — such as nylon inserts — is installed after coating is complete.
Parts are hung on grounded racks and moved into the powder booth. The spray gun imparts a negative electrostatic charge to the powder particles as they leave the gun — the grounded part attracts the charged powder uniformly across all surfaces, including edges and recessed areas that liquid paint misses. Coverage is even, consistent, and waste is minimal.
Coated parts enter the cure oven at 350–400°F. Heat causes the powder particles to melt, flow together, and chemically cross-link into a continuous, uniform film. The result is a finish that is significantly harder, thicker (0.002–0.004″), and more impact- and corrosion-resistant than liquid paint. Parts are inspected for film thickness, coverage, adhesion, and color before delivery.
Powder coating is far more than just color. The combination of gloss level, texture, and powder chemistry creates dramatically different appearances and surface properties — from a mirror-smooth high gloss to a rugged textured wrinkle finish.
High-reflectivity smooth finish. Clean, professional appearance with maximum color depth. Standard gloss for industrial enclosures, equipment panels, and parts requiring a polished look. Available in the full RAL color range.
60–90 GU GlossModerate sheen — the most popular finish for commercial and industrial applications. Reduces surface glare in high-visibility environments, hides minor surface imperfections better than full gloss, and provides excellent durability. Preferred for many generator enclosure and equipment panel applications.
25–55 GU GlossNon-reflective finish with a soft, even appearance. Ideal where glare reduction is required, for parts that will be repainted or over-coated, or for architectural and aesthetic applications requiring a subdued look. Also common for military and government specification parts.
< 15 GU GlossA fine-grained surface texture that masks weld lines, surface scratches, and minor forming marks — popular for sheet metal enclosures where cosmetic surface quality varies. Provides grip and scratch resistance and is commonly specified for outdoor equipment and industrial housings.
Smooth to Medium GrainMetallic mica or aluminum flake particles dispersed in the powder create a sparkling metallic appearance — silver, gold, bronze, and custom metallic blends available. Popular for architectural, automotive, and consumer-facing applications requiring a premium appearance.
Mica & Aluminum FlakeA distinctive dimpled or hammered surface pattern that provides excellent coverage over weld seams and surface variations. The wrinkle finish is a classic industrial look — durable, functional, and visually distinctive. Available in black, grey, green, and other standard colors.
Hammered · Wrinkle PatternPowder coating is available in virtually any color from the RAL Classic and RAL Design system — the European standard for color specification used universally in manufacturing and fabrication.
Common stock colors — flat black, gloss white, safety yellow, safety orange, grey, and others — are typically available without minimum quantity requirements. Custom or specialty colors may require minimum quantity.
Provide the exact RAL number, gloss level (flat/satin/gloss), and texture (smooth/fine texture/wrinkle) on your print or quote request. For color-matching an existing part, provide a physical sample or the brand and RAL code used on the original coating. "Powder coat black" alone is not sufficient — there are dozens of blacks with significantly different gloss and hue.
Screen colors are approximate. Specify by RAL code for precise color matching.
Powder coating is suitable for any metal that can withstand curing temperatures of 350–400°F. Lasertech coats the same materials we fabricate — steel, stainless, and aluminum — with consistent results across all three.
The most common powder coating substrate. Excellent adhesion with proper pretreatment. Iron phosphate conversion coating enhances corrosion protection significantly.
Powder coating bonds well to galvanized surfaces with proper surface prep. Provides an additional corrosion barrier for outdoor and high-humidity applications.
Powder coating on aluminum provides excellent corrosion and UV protection. Chromate or zirconium conversion coating pretreatment is recommended for best adhesion.
Stainless can be powder coated for decorative or additional chemical resistance purposes. Surface prep is critical — abrasive blasting creates the necessary adhesion profile.
The decisions made at the design and print stage directly affect the quality and cost of the powder coat finish. Following these guidelines ensures your parts coat correctly the first time.
Questions about how to specify your powder coat finish? Contact our team — we'll help you determine the right color, chemistry, pretreatment, and masking approach for your application and environment.
Include RAL number, gloss level, and texture on the print or PO. "Black" or "powder coat grey" is insufficient — specify the exact RAL code, gloss (flat/satin/semi/gloss), and texture (smooth/fine texture/wrinkle) to ensure a consistent, repeatable finish.
Powder adds 0.002–0.004″ per coated surface. Holes close to thread minor diameter, precision bore fits, and mating stack-up tolerances should be designed with this buildup in mind — or specify masking of critical features.
Call out all surfaces, holes, and features that must remain uncoated — thread IDs, electrical contact areas, precision bores, and grounding points. Use leaders or area shading on the drawing to clearly identify masked zones.
Nylon inserts, rubber grommets, O-rings, and electronics must be installed after powder coating — cure temperatures of 350–400°F will damage or destroy them. Note "hardware installed post-coat" on the print for applicable components.
Welding after powder coating burns and degrades the coating around the weld zone and produces hazardous fumes from coating decomposition. All welding must be completed and cleaned before parts enter the coating process.
Although the same RAL number describes a specific color, slight variations exist between powder coat brands. If you prototype with a specific brand and color, specify it for production as well to ensure a consistent match across batches.

Common questions about powder coating services at Lasertech Metal Works.
Powder coating is a dry finishing process where electrostatically charged powder particles are sprayed onto a grounded metal part. The coated part is cured in an oven at 350–400°F, where the powder melts and chemically cross-links into a durable, uniform protective film — harder, thicker, and more resistant than conventional liquid paint.
Outsourcing adds transportation time, vendor scheduling delays, and a quality handoff risk between fabrication and coating. In-house finishing keeps everything under one roof — the same team that fabricated your parts oversees their coating. Lead times shrink from weeks to days, quality issues are caught before delivery, and there is one point of contact for the entire order.
Powder coating is available in any RAL color. Gloss options include flat/matte, satin, semi-gloss, and full gloss. Textures include smooth, fine texture, and wrinkle. Specialty finishes — metallic, hammertone, candy, and clear — are also available. Specify the exact RAL number, gloss level, and texture on your print for precise color matching.
Any metal that can withstand 350–400°F cure temperatures — mild steel, galvanized steel, stainless steel, and aluminum alloys. Parts with heat-sensitive components (nylon inserts, rubber seals, electronics) must have those components installed after coating is complete.
Standard film thickness is 0.002–0.004″ (2–4 mils) per coated surface. This adds up on features where multiple surfaces are coated — threaded holes may need to be tapped after coating, and precision bores or mating surfaces should be masked or accounted for in the design. Flag critical dimensions and we'll ensure those areas are masked appropriately.
