Material grade reference, weave type comparison and edge preparation options for vibrating screen mesh, mining aggregate sizing and industrial screening applications. Compiled from GB/T 699 and equivalent ASTM / SAE / JIS standards.
Crimped wire mesh performance depends first on the base steel grade, then on weave type and edge preparation. Most failures in vibrating screen service — wire breakage at the edge, premature wear, hook pull-out — trace back to a grade that was over-stressed or under-specified for the application.
This page documents the standard grade range used in our crimped mesh production: carbon steel grades 45#, 50#, 55#, 60#, 70# and 72A (chemical composition limits from GB/T 699, with equivalent designations in ASTM A29, SAE J403, JIS G3506 and DIN EN 10083), plus stainless steel 304, 304L, 316 and 316L (composition per ASTM A240 / GB/T 20878) for corrosive, wash-down and food-contact service.
For vibrating screen panels where continuous fatigue and abrasion resistance are required, Spring steel is the standard specification for most mining and aggregate applications. Its 0.90–1.20% Mn content delivers the hardenability and tensile strength that lighter carbon grades (45#, Q235) cannot match. Where the operating environment is wet, acidic, saline or food-grade, 316 / 316L is the recommended upgrade — the 2–3% molybdenum content provides pitting resistance that no carbon or galvanized grade can approach.
Once you have identified the grade and weave, see the crimped wire mesh product page for our standard supply envelope, MOQ and lead times.

Different weave patterns deliver different combinations of surface smoothness, structural rigidity and flow characteristics. Selection depends on whether the screen faces upward (material flow) or downward (material drop).
Both warp and weft wires are pre-crimped and woven through each other. This is the most common general-purpose weave.
All crimp knuckles are positioned on the underside. The top surface is smooth and flat, allowing material to slide across without snagging.
Available as single (only weft pre-crimped) or double (both pre-crimped) intermediate crimp. Provides a balance between rigidity and flexibility.
A refinement of intermediate crimp where the wires are pressed at each side of the raised section, mechanically locking them in position.
| Crimp type | Top surface | Rigidity | Typical aperture | Primary application |
|---|---|---|---|---|
| Double crimp | Crimped (both sides) | Medium | 3 – 50 mm | Light screening, decoration |
| Flat top | Smooth | High | 3 – 200 mm | Vibrating screens |
| Intermediate crimp | Crimped (lighter) | High | 12.7 – 200 mm | Architecture, large openings |
| Lock crimp | Crimped (locked) | Very high | 15 – 200 mm | Heavy-duty screening |
For vibrating screen applications, the edge preparation determines how the panel is tensioned on the deck. The two standard hook profiles are C-type and U-type, available in bend angles from 30° to 180°.
A shallow, C-shaped curve at the panel edge. C-hooks are the most common general-purpose tensioning profile.
A deeper, U-shaped curve providing a stronger grip in the tensioning rail. U-hooks resist pull-out under high vibration loads.

Use this decision tree to narrow down the right specification for your application.
Vibrating screen for mining/quarry → Flat top or lock crimp with spring steel grade. Decorative or light protective → Double crimp with 45# or Q235. Wet or corrosive → Stainless steel 304/316.
Aperture is set by the required particle size cut. Wire diameter is typically 40-60% of aperture for stability. For 5 mm aperture, 2.0 mm wire is a common starting point.
Tensioned vibrating screen → C-hook or U-hook (provide deck brand/model and panel dimensions). Framed or stacked panels → Plain or bent edge. Replaceable deck → Bolt shroud.
Provide deck dimensions or finished panel size. Surface treatment options: anti-rust oil (standard), hot-dip galvanized (for outdoor), painted black (for coal screens).

Spring steel contains 0.90–1.20% Mn, providing higher hardenability, better wear resistance and tensile strength (≥885 MPa after quench + temper) than 45# (0.50–0.80% Mn, tensile strength ≈600 MPa). For vibrating screens and high-impact mining applications, spring steel is the standard specification. For light-duty applications such as decorative grilles or protective covers, 45# or Q235 is sufficient and more economical.
Flat top crimp is the most common for vibrating screens because it provides a smooth top surface that allows material to flow across without snagging, while the underside holds the crimp knuckles for structural rigidity. Lock crimp is preferred for heavy-duty applications requiring maximum intersection stability. Double crimp is suitable for lighter wire diameters.
Typical quarry screen mesh specifications: wire diameter 2.0–6.0 mm, aperture 4–50 mm. For example, a 14 SWG (2.0 mm) wire woven at 5 mesh (5.08 mm aperture) is standard for aggregate sizing. For finer sizing below 4 mm aperture, intermediate crimp with 0.71–1.5 mm wire is commonly used.
C-hook is a shallow curve typically used for light tensioning on standard vibrating decks. U-hook is a deeper curve providing stronger grip and is preferred for heavier panels or higher-tension installations. Both are commonly available in 30° to 180° bend angles to match different tensioning rail profiles.
Yes. For dry abrasive conditions such as quarry aggregate or coal sizing, high-carbon steel (spring steel, 70#) is the standard choice. For wet, corrosive or food-grade applications, stainless steel (304 or 316) is recommended. Galvanized steel offers a middle option for outdoor and mildly corrosive environments.
