Sheet Metal Component Overview

Details of L Patti, L Angle Bracket, Corner Bracket

L patti, widely searched as a heavy duty l bracket, l angle bracket, l clamp for wood, or l shaped steel bracket, is the foundation of structural rigidity across commercial furniture and industrial storage frameworks. At Aero Enterprises, we manufacture custom and standard l angle bracket sizes ranging from 25mm to 100mm to match industrial print designs. A standard industrial corner bracket requires absolute precision during stamping to eliminate springback and guarantee a true 90-degree bend. Utilizing our 20T to 50T power presses, we supply mass-manufactured l patti and heavy duty metal l brackets to furniture manufacturers, warehouse rack fabricators, and commercial hardware brands throughout Mumbai, Thane, Navi Mumbai, and Pune.

Component Specifications

What Is L Patti Steel / Heavy Duty L Bracket Hardware

L patti is the common Indian trade name for an L-shaped right-angle corner bracket made from sheet metal or rolled steel. The same component is referred to as an l angle, heavy duty l bracket, l profile patti, or corner angle bracket depending on the industry. In furniture manufacturing, l patti steel brackets are the primary joining hardware for tables, racks, and shelving frames. In industrial fabrication, l angle brackets are used for panel reinforcement, cable tray supports, and enclosure stiffening. The critical performance requirement across all these applications is the same: the two arms of the l patti must form a true 90 degrees within tight angular tolerance, the hole centres must be consistent, and the bend must not open up under repeated load cycles. At Aero Enterprises, l patti brackets are formed on our power press with springback compensation dialled in per material grade and thickness.

Material Comparison

Standard L Patti vs Custom L Angle What You Should Order

Standard l patti steel sizes from 25mm to 100mm arm length are the fastest to produce because tooling is already available on Aero's press floor. If your rack design uses industry-standard hole spacing and equal-arm l angle geometry, you will get faster delivery on standard configurations. Custom l profile patti and asymmetric l angle brackets with non-standard arm lengths, offset hole patterns, or deep notches at the bend require new die setup. This adds 3 to 5 days to the first batch lead time but produces a heavy duty l bracket that fits your product exactly.

HSN & GST Classification

HSN Code of L Patti, L Angle Bracket, Corner Bracket

Fabricated sheet metal l patti steel and l angle corner brackets fall under HSN Code 7326 (other articles of iron or steel, fabricated and stamped). GST rate is 18 percent. This applies to MS, GI, and SS 304 l profile patti and l angle brackets as finished fabricated components.

Frequently Asked Questions

FAQ of L Patti, L Angle Bracket, Corner Bracket

Aero Enterprises believe in keeping things clear and simple. Read through our common questions to understand our supply capabilities, standards, and procurement processes for L Patti, L Angle Bracket, Corner Bracket.

Contact Aero Enterprises

What is L patti and what is the difference between l patti steel, l profile patti, and a heavy duty l bracket?

L patti, l profile patti, and heavy duty l bracket all refer to the same L-shaped right-angle bracket used to connect two structural members at a 90-degree joint. The different names reflect different trade contexts: l patti is the common hardware name in India; heavy duty l bracket is the engineering term; l profile patti is used in the stainless steel hardware segment. We manufacture all of these as stamped components in MS IS 2062, GI IS 277, and SS 304.

What l angle bracket sizes do you manufacture?

Standard l angle bracket sizes available from Aero Enterprises Unit 1 Manufacturing / Fabrication Unit Vasai are 25x25mm, 40x40mm, 50x50mm, 65x65mm, 75x75mm, and 100x100mm, with thickness 1.2mm to 3.0mm depending on the load requirement. Asymmetric l angle brackets with unequal arm lengths (e.g. 50x75mm) and custom l profile patti with non-standard hole patterns are available from new tooling.

Can you manufacture L patti angle brackets with slotted holes for adjustable racks?

Yes. For industrial storage racks, slotted angle shelving, and adjustable furniture frames, we stamp L patti brackets with elongated slotted holes. This provides the installer with 10mm to 15mm of lateral or vertical adjustment during assembly to ensure racks sit perfectly level on uneven factory floors. Specify slotted holes on your drawing when requesting a quote.

What is the correct l patti thickness for furniture joints?

For standard furniture joints on tables, chairs, and racks, 1.5mm MS l patti steel at 40x40mm or 50x50mm is the correct specification. For heavy-duty industrial furniture and steel rack structures carrying above 80kg per shelf, 2.0mm MS l angle at 50x50mm or 65x65mm is required. For lightweight stationery hardware, 1.2mm CR l profile patti at 25x25mm provides adequate stiffness.

What surface finish options are available for l patti hardware?

Electrostatic powder coat over 7-tank zinc phosphate pretreatment is the standard finish for indoor industrial l patti steel brackets, applied at 60 to 80 microns DFT. Available colours: black RAL 9005, grey RAL 7035, white RAL 9003, and zinc silver. GI IS 277 base material is used for l angle brackets in outdoor applications needing zinc-layer protection without paint.

Can l patti steel be used for outdoor applications?

MS IS 2062 l patti with powder coat is adequate for sheltered outdoor applications. For fully exposed heavy duty l bracket installations like outdoor rack structures or solar frame corner joints, GI IS 277 l profile patti is the correct specification. The zinc layer in GI at 120 GSM provides corrosion protection independent of paint for approximately 15 to 20 years.

Can you supply l patti hardware with countersunk holes?

Yes. Countersunk holes for flat-head screws are available in M4, M5, and M6 on both arms of the l shaped steel bracket. Standard countersink angle is 90 degrees. Countersunk l patti hardware is commonly used in furniture applications where the screw head must sit flush with the bracket surface to avoid contact damage to the furniture panel.

What is the minimum order quantity for l patti corner brackets?

For standard l angle bracket sizes using existing tooling, minimum order is 200 pieces. For custom l angle sizes with new die setup, minimum first batch is 500 pieces to amortise tooling cost. We package bulk OEM orders in 25kg or 50kg gunny bags for secure transit across Maharashtra.

Do you supply l profile patti in stainless steel for kitchen applications?

Yes. SS 304 ss l patti brackets are available for commercial kitchen fixtures, food processing equipment frames, and hygiene-critical hardware. SS 304 l patti is supplied with a natural 2B finish or brushed finish depending on specification. Specify SS grade only where the application genuinely requires it.

How does Aero Enterprises ensure 90-degree accuracy in l patti steel manufacturing?

At Aero Unit 1 Manufacturing / Fabrication Unit, l patti corner brackets are formed on a power press with springback compensation programmed per material grade and thickness. Without compensation, an l patti steel bracket formed to 90 degrees in the die will open to 91 to 93 degrees after the press releases. Aero's power press overbends by the calculated springback angle so the final released angle is exactly 90 degrees.
