1. The Backbone: Why Q235B Steel Matters

Every padel court starts with a steel frame. The steel grade, thickness, and profile design determine structural integrity, wind resistance, and how the court performs over decades of use. Not all steel is created equal.

What Is Q235B Steel?

Q235B is a Chinese national standard carbon structural steel defined under GB/T 700-2006. It is widely used in construction, bridges, and industrial manufacturing. For padel courts, Q235B offers the optimal balance of strength, weldability, and cost-effectiveness.

Property	Q235B	Inferior Alternative
Yield Strength	235 MPa minimum	< 200 MPa (deforms under load)
Tensile Strength	370-500 MPa	Unspecified — unpredictable failure
Weldability	Excellent (low carbon)	Poor — weld cracking risk
Thickness Tolerance	≥ 3mm for corner posts	2-2.5mm — noticeable flex in wind
Standard Reference	GB/T 700-2006	No standard code

Profile Design: How Steel Shape Affects Stability

PeakPadel uses three distinct profile designs across our product range, each engineered for a specific use case:

• 80×60×3mm Double-Stacked (Economics A) — Two rectangular tubes welded together for maximum rigidity at an entry-level price point. The stacked design increases the moment of inertia without adding excessive weight.
• 100×100×3mm Square Post (QF / PRO / WPT) — Symmetrical square profile for uniform load distribution. The larger cross-section provides superior torsional resistance, ideal for high-wind zones and tournament venues.
• 100×50×3mm Rectangular Crossbeam — Used horizontally for fence frames and light poles. The rectangular profile resists bending in the primary load direction while saving material weight.

2. 12mm Tempered Glass — Safety You Can't Compromise

Padel is unique among racket sports because the glass walls are part of the playing surface. Players hit the ball off the glass, bodies collide with panels, and the glass must absorb high-velocity impacts thousands of times per day. This is why 12mm tempered glass is the industry standard — and why anything thinner is a liability.

Tempered vs. Standard Glass: The Difference

Tempered glass undergoes controlled thermal treatment: it is heated to ~620°C and rapidly cooled. This process creates compressive stress on the surface and tensile stress inside, making it 4-5 times stronger than annealed glass of the same thickness.

More importantly, when tempered glass does break, it shatters into small, relatively harmless granular pieces rather than dangerous sharp shards — a critical safety feature when players are routinely in contact with the panels.

Glass Type	Strength	Break Pattern	Padel Suitable?
12mm Tempered	4-5x annealed	Small granular pieces	Yes — industry standard
10mm Tempered	~3x annealed	Small granular pieces	Marginal — higher risk of spontaneous breakage
Laminated Tempered	5-6x annealed	Fragments held by interlayer	Premium option — ideal for high-traffic venues
Annealed (non-tempered)	1x baseline	Large sharp shards	Unsafe — should never be used

Why 12mm Specifically?

The 12mm specification emerged from decades of padel court engineering. At 10mm, panels can develop micro-cracks around mounting points after 2-3 years of play. At 12mm, the increased cross-section distributes impact forces more evenly, extending panel life to 10+ years in normal conditions. The extra 2mm also provides better ball rebound consistency — an important characteristic for competitive play.

3. Hot-Dip Galvanizing vs. Paint: The Anti-Rust Truth

Steel rusts. The question is not whether your court will face corrosion — it is when. The anti-rust treatment you choose determines whether that timeline is 3 years or 30 years.

The Two-Layer Protection System

PeakPadel applies a dual-layer protection process that is standard across all our court models:

Layer 1 — Hot-Dip Galvanizing: Steel components are immersed in molten zinc at ~450°C. The zinc metallurgically bonds to the steel surface, forming a series of zinc-iron alloy layers topped with pure zinc. This creates a robust barrier that prevents moisture and oxygen from reaching the steel.

Layer 2 — Polyester Powder Coating: After galvanizing, components receive a polyester powder spray applied electrostatically, then baked at high temperature. The powder melts and cures into a uniform, durable finish. PeakPadel applies two coats for a total thickness of 150–300 microns — significantly above the industry average of 60–100 microns.

Protection Method	Coating Thickness	Lifespan (Outdoor)	Cost
Paint Only	30-60μm	2-4 years (flaking, rust)	Lowest upfront
Powder Coating Only	60-100μm	4-8 years	Moderate
Hot-Dip + Powder (PeakPadel)	150-300μm	15-25+ years	Best long-term value
Stainless Steel Frame	N/A	30+ years	Prohibitively expensive

4. SUS304 Stainless Steel Fittings: The Hidden Detail

Screws, nuts, bolts, and washers are the smallest components of a padel court — and among the most consequential. A court with 10,000 rusted fasteners is a court that will fail inspection, frustrate players, and require costly hardware replacement within years.

Why SUS304 Specifically?

SUS304 is the Japanese Industrial Standard designation for 18/8 stainless steel (18% chromium, 8% nickel). It offers:

• Corrosion resistance in atmospheric environments, fresh water, and most chemical exposures
• Non-magnetic in annealed condition — no interference with nearby electronics
• Excellent formability for precision threading
• Temperature tolerance from cryogenic to ~870°C intermittent

Many manufacturers cut costs by using galvanized steel fasteners instead of SUS304. Galvanized fasteners will show rust spotting within 12-24 months in outdoor conditions, particularly around the threaded areas where the zinc coating is thinnest. The result is visible rust streaks on white court panels — a cosmetic and structural problem that erodes player confidence.

Fitting Material	Rust Starts	10-Year Outcome	Recommendation
SUS304 Stainless	20+ years (virtually never)	Clean, functional	Required for outdoor courts
Galvanized Steel	12-24 months outdoor	Rust streaks, seized threads	Indoor only
Zinc-Plated Carbon Steel	6-12 months outdoor	Severe corrosion, unsafe	Unacceptable

5. Artificial Turf: Density, Pile Height, and Standards

The surface you play on affects ball bounce consistency, player comfort, and injury risk. Padel turf is specifically engineered — it is not the same product used for landscaping or soccer fields.

Key Turf Specifications

• Pile Height: 10mm or 12mm — shorter than tennis turf (typically 15-19mm) to produce the characteristic fast, low bounce of padel. Taller pile slows the game and creates inconsistent ball behavior.
• Density Options: PeakPadel offers three density tiers, with the highest reaching 63,000 stitches/m². Higher density provides more uniform ball roll, better wear resistance, and a more premium underfoot feel.
• Standard Compliance: GB/T 20394-2019 — the Chinese national standard for sports artificial turf, covering pile height tolerance, tuft bind strength, UV aging resistance, and heavy metal content.
• Infill: Silica sand infill is recommended for 10-12mm padel turf. The sand adds weight to keep the turf flat, provides shock absorption, and helps the turf fibers stand upright for consistent ball contact.
• Color Options: Available in green, blue, red, pink, and custom colors to match your club's branding.

Turf Density: Why It Matters

Higher-density turf lasts longer, plays better, and costs more. Here is what different density levels mean in practice:

Density Tier	Stitch Rate	Best For	Expected Lifespan
Standard	~40,000/m²	Indoor / light-use recreational	3-5 years
Competition	~52,000/m²	Club-level daily use	5-7 years
Premium (PeakPadel top tier)	63,000/m²	Tournament / high-traffic commercial	7-10 years

6. How Materials Translate to Court Models

Understanding materials helps you decode court model comparisons. Here is how the five materials covered above map to PeakPadel's product range:

Model	Steel Profile	Glass	Anti-Rust	Turf Option
Economics A	80×60×3mm (double-stacked)	12mm tempered	Hot-dip + powder coat	Standard to Premium
Economics B	80×80×3mm	12mm tempered	Hot-dip + powder coat	Standard to Premium
QF / PRO	100×100×3mm	12mm tempered	Hot-dip + powder coat	Competition to Premium
WPT Tournament	100×100×3mm	12mm tempered	Hot-dip + powder coat	Premium (63,000/m²)

Every model shares the same core material standards: Q235B steel, 12mm tempered glass, hot-dip galvanizing, SUS304 fittings, and GB/T 20394-2019 turf. The differences are in profile dimensions, turf grade, and optional features like lighting and roofing. Even our entry-level Economics series uses the same anti-rust process and glass specification as our tournament-grade WPT model — because we do not compromise on the materials that keep players safe and courts standing.

Materials Checklist for Buyers

Before you order, verify these five specifications with your manufacturer. If any answer is vague, ask for documentation:

1. Steel: Is it Q235B per GB/T 700-2006? What is the minimum wall thickness for corner posts?
2. Glass: Is it 12mm tempered? Can the manufacturer provide a tempering certificate?
3. Anti-Rust: Does the process include hot-dip galvanizing? What is the total coating thickness?
4. Fittings: Are screws, nuts, and washers SUS304 stainless steel? This should be written in the specification sheet.
5. Turf: What is the stitch rate (density)? Does it comply with GB/T 20394-2019 or equivalent?
