Metal Fabrication for Agricultural Equipment
Laser-cut, bent and welded parts for irrigation, greenhouses and farm machinery in Egypt, the UAE and Saudi Arabia
Agricultural equipment sees sun, sand, fertiliser and washdown water, so parts fail either by rust or by abrasion long before fatigue. CutLinq laser cuts, bends and welds brackets, frames, guards and sieve panels for irrigation systems, greenhouses, feed and grain handling, and towed implements across Egypt, the UAE and Saudi Arabia. Most parts are galvanised or stainless mild steel, cut in the 1.5-8 mm range that covers brackets and guards.
This page covers the grades used for field exposure, the surface protection that survives dust and fertiliser salts, and the parts CutLinq fabricates most often for farm equipment builders and repair workshops.
Materials for field exposure
Galvanised mild steel DX51D+Z275 is the default for structural brackets, frames and guards because the 20-40 µm zinc coating survives dust abrasion and occasional wetting from irrigation. Stainless 1.4301 (304) is used where the part contacts fertiliser, feed or wash-down chemicals, since zinc corrodes faster than steel in ammonia-bearing environments.
Aluminium EN AW-5754 is chosen for lightweight covers and panels on mobile equipment where reducing towed weight matters, and for greenhouse cladding frames that must not rust in permanently humid, warm air.
| Material | Typical thickness | Use | Field life |
|---|---|---|---|
| DX51D+Z275 galvanised | 1.5-6 mm | Brackets, guards, frames | 10-15 years, dry-arid |
| S235JR + hot-dip galv. | 3-12 mm | Structural frames, towbars | 15-20 years, ISO 1461 |
| 1.4301 (304) stainless | 1-4 mm | Feed, fertiliser contact parts | 20+ years |
| EN AW-5754 aluminium | 1.5-4 mm | Covers, greenhouse frames | 15-20 years |
| Woven / perforated mesh | 0.8-3 mm perf | Sieves, screens, ventilation | 5-10 years, abrasion limited |
Common parts and processes
Irrigation systems need laser-cut brackets and clamps for pipe runs, usually 2-4 mm galvanised steel with countersunk holes for anti-theft fasteners common on remote field installations. Greenhouse structures use bent and welded steel or aluminium frames with tolerances of ±1 mm on frame width so polycarbonate or film cladding fits without gaps.
Grain and feed handling equipment uses perforated stainless or galvanised sheet for sieves and screens, laser cut with hole patterns from 2 mm to 12 mm depending on the product graded, and CNC bent hoppers and chutes with a 3-5 mm plate thickness for wear resistance.
- Pipe clamps and brackets: 2-4 mm galvanised steel, laser cut
- Greenhouse frame sections: 20x20 to 40x40 mm box or angle, bent and welded
- Sieve and screen panels: perforated 1.5-3 mm sheet, hole sizes 2-12 mm
- Hopper and chute plate: 3-6 mm mild steel or 4-8 mm for abrasive grain
- Machinery guards: 2-3 mm perforated or expanded mesh, laser cut edges
Corrosion and wear in Gulf and Egyptian field conditions
Sand abrasion in the Nile Delta, Saudi interior and UAE desert farms wears through thin galvanising within 3-5 years on parts that drag or vibrate against soil; specify 6-10 mm plate or a wear-resistant liner on chutes and skids rather than relying on coating thickness alone.
Fertiliser residue is corrosive to zinc; wash-down points and fertiliser hoppers should use 304 stainless or an epoxy topcoat over galvanising rather than bare zinc. In coastal Gulf farms, salt-laden humidity accelerates both rust and zinc consumption, so exterior frames near the coast benefit from duplex protection (galvanise plus powder coat).
Design tips
- Specify hot-dip galvanising (ISO 1461, 45-85 µm) rather than electroplated zinc (5-12 µm) for any part left outdoors.
- Round all exposed edges to at least 1 mm radius; farm equipment is handled without gloves in the field.
- Add drainage holes of 6-8 mm diameter at the lowest point of hollow box sections before galvanising.
- Use slotted rather than round mounting holes (±3 mm slot) to absorb frame misalignment from field assembly.
- For sieve and screen mesh, oversize the frame opening by 2-3 mm per metre to allow for thermal expansion.
- Order fertiliser-contact parts in 1.4301 (304) minimum; do not substitute galvanised steel to save cost.
- Group small brackets on one nesting layout to cut per-part laser cost for high-volume irrigation projects.
Applications
| Industry | Example parts | Typical material |
|---|---|---|
| Irrigation | Pipe clamps, valve brackets, filter housings | DX51D+Z galvanised 2-4 mm |
| Greenhouses | Frame sections, gutter brackets, vent hardware | S235JR galvanised, EN AW-5754 |
| Grain and feed handling | Sieves, hoppers, chutes, augers guards | 1.4301 stainless, S235JR 3-8 mm |
| Livestock equipment | Pens, feeders, ventilation frames | Galvanised steel, 304 stainless |
| Towed implements | Hitch plates, tool bars, guard mesh | S355J2 6-12 mm |
| Farm workshops | Repair brackets, replacement guards | S235JR, DX51D+Z |
Pricing and lead time
Price is driven by material (galvanised sheet costs 15-20% more than bare mild steel per kg, and 304 stainless roughly 3-4 times), by finishing (hot-dip galvanising adds a fixed batch cost that is more economical above 20-30 kg per order), and by hole count on perforated sieve panels, which slows laser cutting significantly. Laser-cut and bent brackets are typically ready in 3-5 working days; hot-dip galvanised structural frames 7-10 working days across Egypt, the UAE and Saudi Arabia, since galvanising is batched at a separate facility.
Frequently asked questions
Galvanised DX51D+Z is sufficient for brackets that only see soil and irrigation water. Switch to 1.4301 stainless only where the part also contacts fertiliser concentrate or chlorinated cleaning solution.
