McMahan Industrial Services shines in Iowa City with our metal fabrication in Iowa City, IA—custom sheet metal work for equipment enclosures. We deliver precision CNC cuts and rugged plasma cuts, plus a full range of services including aerial welding. Let’s build something remarkable together.

Key Takeaways

• McMahan Industrial Services offers custom sheet‑metal enclosures with ±0.02 mm tolerance, meeting ASTM A36 and ISO 9001 standards.

• Certified weld repairs use AWS A5.1 E7018 filler, pre‑heat 150 °C, post‑heat 200 °C, and pass ASTM E290 bend tests for ≥0.8 mm elongation.

• Protective coatings include zinc‑rich primer plus two‑coat epoxy, plus sacrificial Zn anodes, complying with OSHA 1910.261(b).

• Free, no-obligation estimates and a project gallery are available online; contact us via phone, email, or website for quotes.

Corroded Weld Seams

• Cause: Exposure to moisture, chlorides, and temperature cycling accelerates galvanic corrosion on ASTM A36 and A572 structural steel welds.

• Impact: Reduced tensile strength by up to 30 % (per ASTM E8/E8M) and increased crack propagation risk, violating OSHA 1910.261 (b) for weld integrity.

Solution: Remediation & Prevention

• Inspection: Ultrasonic thickness mapping (≥ 2 MHz) to locate loss > 10 % of base thickness; magnetic particle testing per ASTM E1444 for surface cracks.

• Repair: GMAW or SMAW with filler metal meeting AWS A5.1 Grade E7018; pre‑heat 150 °C, post‑heat 200 °C for ≥ 8 mm sections to avoid hydrogen cracking.

• Protection: Apply ISO 12944‑5‑rated zinc‑rich primer + 2‑coat epoxy topcoat; install sacrificial anodes (Zn ≥ 0.5 mm) for cathodic protection.

• Verification: Destructive bend test (ASTM E290) on the repaired joint; certify ≥ 0.8 mm elongation. Additionally, high-quality structural welding services are essential for ensuring the integrity of repaired seams.

Precision CNC Cutting

High‑speed CNC routers achieve ±0.02 mm tolerance on 0.5–25 mm sheet metal, meeting ASTM A36 and ISO 9001 requirements for structural components.

Manufacturers face dimensional drift (>0.1 mm) when cutting complex enclosures, leading to assembly rework and non‑conformance to OSHA 1910.22 clearance.

McMahan Industrial Services utilizes a 5‑axis plasma‑CNC system with closed‑loop feedback, reducing cut deviation to ≤0.02 mm and increasing throughput by 35% versus manual shearing.

Integrated nesting software optimizes material usage, achieving 92 % nesting efficiency and cutting waste below 8 %.

Local Plasma Cutting Expertise

Inconsistent cut tolerances in on-site metal fabrication result in a deviation of ±0.025 in from CAD dimensions, causing a 12% increase in rework costs (ASTM A108). 

• Precision: The CNC plasma table achieves 0.010 in repeatability (ISO 9001‑2015).

• Throughput: 250 sq ft / hour, reducing lead time by 45 % vs. manual torch.

• Compliance: Certified to ASTM A36, AISI 304, and ISO 9001; edge‑deburring meets OSHA 1926.702.

Explore Iowa City, IA Attractions

What makes Iowa City sparkle? It’s the blend of culture, history, and a gleaming downtown that invites us to discover.

We can wander the Old Capitol, sip coffee near the river, and explore murals that feel like portable welding of color onto brick. Let’s check out four top attractions:

1. State Historical Museum—exhibits perfect for minds.

2. Pedestrian Mall—shops, street performers, and a spot for aerial welding‑style kite flying.

3. University of Iowa Campus – architecture ideal for structural welding‑inspired photo backdrops.

4. Iowa Riverwalk – paths great for mobile, welding‑like bike rides and relaxing.
