A padel club in Kochi opened in 2022 with two courts. The padel court steel frame on each court was quoted as "galvanized finish steel", which sounded right. Eighteen months later, rust streaks appeared on the vertical columns, concentrated at the weld joints. The courts were 3km from the coast.
What the contractor had supplied was powder-coated steel, not hot-dip galvanized. In a coastal location, that is the wrong specification. By 2024, the rust had reached the base plate bolt connections. A structural engineer assessed the frames and recommended urgent treatment. Sanding, rust treatment, and recoating cost Rs 1.2 lakhs per court, and the frames will need the same treatment every two to three years.
A hot-dip galvanized frame would have cost Rs 1.8 lakhs more per court at the time of construction. One payment. Done.
This article explains what the padel court steel frame actually does, why the material grade matters, how to read a contractor's frame specification, and what a correctly specified frame costs in India.
What the Steel Frame Actually Does
The steel frame is not a mounting bracket for the glass panels. It is the structural skeleton of the entire court. It does five jobs simultaneously:
- Holds the tempered glass panels under permanent tension load
- Absorbs dynamic loads from players hitting the walls at speed
- Resists wind uplift, which is significant on open or elevated sites
- Supports the net post, fencing mesh, and lighting brackets where these attach to the structure
- Transfers all these loads down to the concrete slab anchor points
A padel court takes structural punishment. Players run into the back glass walls at full sprint. The glass flexes slightly under high-speed ball impact, and the frame must absorb that flex without transferring stress to the panel edges, where glass is most vulnerable to fracture.
An underspecified frame — one that uses thinner section sizes than the structural load requires — flexes more than it should. Over time, that excess movement creates micro-stress at the glass-to-frame connection point. Glass does not shatter from this. It develops hairline cracks, then cracks, then fractures. The cause looks like spontaneous glass failure. The real cause is frame flex.
Getting the frame right isn't a luxury specification. It's the structural foundation that everything else depends on.
The Three Frame Material Options in India
When you receive a padel court quote in India, the frame will be described as one of these three. They are not equivalent.
1. Powder-Coated Steel
Powder coating applies fine pigmented powder to the steel electrostatically, then cures it under heat to form a hard surface coating.
Coating thickness: 60–80 microns in standard commercial applications.
Suitable for: Dry inland locations with no coastal salt air and less than 800mm annual rainfall. Delhi NCR, Gurgaon, Noida, Jaipur, Lucknow, Chandigarh, interior Maharashtra, parts of UP and Punjab. For these North India locations, properly applied powder coat on primed steel is the correct specification — you are not paying for corrosion protection you don't need. The concern in these locations is not corrosion but thermal expansion (see below).
Not suitable for: Any coastal location within 5km of the sea. Salt aerosol penetrates powder coating within three to five years. Once the coating fails, bare steel corrodes rapidly, and the failure accelerates at weld points and cut edges where the coating is thinnest.
Cost indicator: The cheapest frame option. Found in budget builds in the Rs 15–20 lakh total court cost range.
2. Cold-Galvanized (Zinc Spray or Zinc-Rich Paint)
Cold galvanizing applies zinc-rich paint by spray or brush. It provides more corrosion protection than plain powder coat, but significantly less than hot-dip galvanizing.
Coating thickness: 40–60 microns claimed. Actual thickness varies depending on application quality and how many coats were applied.
The India market problem: Many contractors describe their frames as "galvanized" when they mean cold-galvanized or zinc-spray finished. The word "galvanized" in a padel court quote almost always refers to the cheaper cold-galvanized process unless the quote specifically states hot-dip.
Cold-galvanized zinc sits on the steel surface. It does not bond metallurgically. At weld joints and cut edges, moisture finds its way under the zinc layer. This is where corrosion starts.
3. Hot-Dip Galvanized (HDG)
Hot-dip galvanizing submerges fabricated steel sections in a bath of molten zinc at approximately 450°C. The zinc reacts with the steel surface and forms a series of zinc-iron alloy layers, capped by pure zinc. The coating is part of the steel, not a surface layer on top of it.
Coating thickness: Minimum 85 microns for structural sections. In practice, structural sections typically achieve 90–100 microns.
Suitable for:
- All coastal locations within 5km of the sea: Mumbai, Chennai, Kochi, Goa, Vizag, Kolkata, Pondicherry
- High-humidity inland cities: Bangalore, Hyderabad, Pune, Mangalore, Nashik
- Any outdoor court site receiving more than 800mm annual rainfall
Lifespan: A properly hot-dip galvanized frame in a non-coastal Indian location will last 20–25 years before any significant corrosion begins. In coastal locations, HDG with an epoxy topcoat can last 25–30 years.
Cost premium over powder coating: Rs 1.5–2.5 lakhs per court for the frame. Over a 15-year period on a coastal site, this premium pays for itself several times over in avoided maintenance and frame replacement costs.
Section Sizes: What the Numbers in a Quote Actually Mean
A properly specified frame quote should list the steel section dimensions used for each structural element. If a quote says only "MS steel frame," that tells you nothing about structural adequacy.
MS = mild steel. It describes the material but not the size, thickness, or structural grade.
Here is what a padel court frame specification should include:
SHS = Square Hollow Section. RHS = Rectangular Hollow Section.
Corner posts take the highest impact loads on a padel court. Players hit the back glass hard, and the corners are where two glass panels meet at the tightest connection. These sections should be heavier than the main columns.
Steel grade: Ask for S275 structural grade minimum. This is the standard for structural steelwork. Ask for S355 (the heavier commercial grade) on corner posts and net posts, where the impact loads are highest.
If a contractor can't provide section dimensions when asked, that's a significant warning sign.
How India's Climate Changes the Frame Specification
India is not one climate. The correct frame specification depends on where you are building.
Coastal Salt Air (Mumbai, Chennai, Kochi, Goa, Vizag and all coastal cities)
Salt aerosol is present in the air within 5km of the Indian coastline. Salt particles settle on steel surfaces, retain moisture, and dramatically accelerate the electrochemical process of corrosion.
For these locations, hot-dip galvanized is the minimum acceptable specification. Some suppliers offer HDG plus an epoxy powder topcoat for the most aggressive coastal environments (within 1km of the sea). This adds Rs 50,000–80,000 per court but extends frame life to 30 years.
The galvanizing coating thickness requirement increases with proximity to the coast:
- 5km from coast: 85 microns HDG
- 2km from coast: 85 microns HDG + epoxy topcoat
- Within 1km: Full corrosion protection system — consult a structural engineer
Monsoon High-Humidity Zones (Western Ghats, Northeast)
Pune, Nashik, Mangalore, Coorg, and cities in the Western Ghats rainfall belt receive 1,000–1,500mm of rain annually. The steel frame is wet for 90–120 days per year. Weld points and connection details are the vulnerable zones.
For these locations: hot-dip galvanized is the correct specification. Powder coat will show rust at weld joints within five to seven years.
High-Temperature Inland Locations (Delhi, Rajasthan, Interior Maharashtra)
The concern here is not corrosion but thermal expansion. Steel expands in heat and contracts in cold. A 20m padel court frame in Delhi experiences a temperature range of approximately 5°C in winter to 42°C in summer. This creates roughly 8–12mm of length change across the full court.
Good frame systems account for this in the glass rebate design — the slot that holds the glass panel edge. The rebate must have enough clearance to allow thermal movement without pressing against the glass edge.
Ask any frame supplier explicitly: "Does your glass rebate design account for thermal expansion in Indian summer conditions?" The correct answer is yes, with a specific tolerance value.
Frame Costs in India: The Honest Breakdown
Frame cost depends on source (imported versus locally fabricated) and treatment specification.
On imported vs locally fabricated: Spanish and Portuguese frame manufacturers have engineered padel court structures for 20+ years. Section sizes, connection details, and glass rebate tolerances are refined through tens of thousands of courts worldwide. Local Indian fabricators work from basic drawings, and the quality of those drawings varies considerably between fabricators.
Local fabrication is acceptable for private residential courts or low-use club courts with a 10–12 year design life. For a commercial club running eight to twelve hours of court time per day, with five to seven days a week of play, the cumulative structural load is significant. An established imported frame manufacturer is the safer choice.
The frame represents 25–35% of total court cost. It is the most difficult and expensive element to replace after the court is built.
8 Questions to Ask Your Contractor About the Frame
Before you sign a padel court construction contract, get written answers to these:
1. Is the frame hot-dip galvanized or powder-coated?
Get this in writing. "Galvanized" alone in a quote means nothing specific. Ask: hot-dip or cold-galvanized?
2. What is the galvanizing coating thickness in microns?
For coastal and humid-zone sites: minimum 85 microns, certified to IS 2629 or EN ISO 1461.
3. What are the main column section dimensions and wall thickness?
Minimum: 100×100mm SHS, 4mm wall thickness.
4. What steel grade?
S275 structural grade minimum. S355 for corner posts.
5. Who manufactured the frame?
Established manufacturer with verifiable project history, or custom local fabrication? Ask for a list of completed courts using the same frame system.
6. Does the glass rebate design account for thermal expansion?
Yes or no. If the answer is uncertain, the manufacturer has not designed for Indian conditions.
7. How is the frame connected to the concrete slab?
Bolt-down base plates into cast-in anchors is the correct method. Bare screw anchors into the concrete surface are not acceptable.
8. What is the structural warranty on the frame?
Minimum five years on frame structure and coating.
FAQ: Padel Court Steel Frame in India
How long does a padel court steel frame last in India?
A hot-dip galvanized frame in a non-coastal location: 20–25 years before significant corrosion begins. A powder-coated frame on a coastal site: 3–6 years before visible rust, 7–10 years before structural treatment is needed. HDG in coastal conditions: 20+ years with correct specification.
Can a locally fabricated steel frame be used for a commercial padel club?
Yes, if the fabricator works from detailed structural drawings, uses certified S275 or S355 steel, and applies hot-dip galvanizing from a certified HDG plant (not spray galvanizing). Visit the fabricator's facility. Ask to inspect the completed frame sections before installation.
What is the difference between a panoramic padel frame and a standard frame?
A standard padel court has glass only on the back walls and the first 2m panel of the side walls. A panoramic court has glass along the full length of the side walls — nine panels instead of four. The panoramic frame is more complex, uses heavier corner connections, and adds Rs 8–15 lakhs to the frame cost. It also improves court visibility, which matters for clubs selling court time.
What are the FIP-standard padel court frame dimensions?
Per FIP specification: court length 20m, court width 10m. Back walls 3m high (glass). Side wall glass section: 3m high for the first 2m from the back wall, transitioning to 1m metal mesh on top of a 0.5m solid base for the remaining length. Any frame that deviates from these dimensions is not FIP-compliant.
Does the frame come with the glass panels, or are they separate?
For imported padel courts, the frame and glass panels come as a matched system from the manufacturer. Glass dimensions are cut to fit the specific frame rebate design. If a contractor is sourcing the frame and glass from different suppliers, confirm in writing that the manufacturers have verified compatibility. Mismatched tolerances cause glass edge stress.
5 Things That Determine Whether Your Frame Will Last
- Material grade matched to your location. Coastal and humid zones: hot-dip galvanized, minimum 85 microns. North India (Delhi, Gurgaon, Jaipur, Lucknow, Chandigarh): powder-coated is the correct choice — no salt air, no need to overspend. But verify thermal expansion clearance in the glass rebates. Get the wrong material grade and you will spend more on maintenance than you saved on the frame.
- Section sizes that match the structural load. Minimum 100×100mm main columns, 4mm wall. Lighter sections flex under repeated player impact and create glass fatigue failure over time.
- Glass rebate tolerance for thermal expansion. Especially important in Delhi, Rajasthan, and extreme summer locations. Ask specifically; do not assume.
- Correct slab anchor connections. The frame is only as strong as its connection to the foundation. Bolt-down base plates into cast-in anchors. Not screw anchors into the surface.
- A manufacturer who has built courts in Indian conditions. Frame engineering for padel is not generic structural steel work. The details at glass connections, base plates, and corner posts matter and require specific padel engineering experience.
Get these five right and a padel court frame will run 20+ years in Indian conditions without structural intervention.
Get them wrong — particularly the material grade in a coastal or humid location — and you will be spending on the frame again within five years.
