Aluminum window hardware is the set of parts that lets a window sash open, hold, close and lock: friction stays or hinges for casement and top-hung windows, rollers for sliding windows, locks and handles, corner joints that hold the profile frame together, and weatherstrips. HIPAD manufactures this hardware for aluminum and uPVC window systems, including friction stays in SS304, SS201 and SS410 from 8 to 24 inches. Window factories, profile system companies and distributors in 60+ countries buy complete sets or single parts from our factory.
An aluminum window is built from extruded profiles, glass and a small set of hardware parts. The hardware does four jobs. Open and hold: friction stays, hinges and restrictors on opening windows, rollers on sliding windows. Lock: crescent locks, keyed locks, lock handles and multi-point locking. Build the frame: corner joints and connectors that join the profiles at each corner. Seal: weatherstrips and brush seals that keep out wind, rain, dust and noise.
The window type decides which parts are needed, and the profile system decides the exact sizes. In Spanish-speaking markets the set is called herrajes para ventanas de aluminio, friction stays are brazos de fricción or compases, and corner joints are escuadras.
Quick answer: a casement (side-hung) window needs two friction stays or hinges, a handle and lock points; a top-hung (awning) window needs two top-hung friction stays and a handle; a sliding window needs two rollers per sash, a crescent lock or lock handle and interlock seals. Every type needs corner joints and weatherstrips.
| Window type | Opening hardware | Locking | Frame and seal | Typical use |
|---|---|---|---|---|
| Casement (side-hung) | 2 friction stays or 2–3 hinges, optional restrictor | Casement handle with cam or multi-point lock | 4 corner joints per sash, weatherstrip | Homes, offices, high-rise |
| Top-hung (awning) | 2 top-hung friction stays | Handle at the bottom rail, lock points | 4 corner joints, weatherstrip | Bathrooms, kitchens, ventilation lights, curtain walls |
| Sliding window | 2 rollers per sash, guides | Crescent lock, lock handle or keyed lock | 4 corner joints, interlock and brush seals | Homes and apartments, especially in Latin America, the Middle East and Asia |
| Fixed light | None | None | Corner joints, glazing seals | Next to opening sashes |

A friction stay (also called a friction hinge or window stay) is a folding steel arm that carries the sash, guides it as it opens and holds it at any angle by friction. It replaces hinges on most aluminum casement and top-hung windows. Choose it by window type, sash size and environment.

| Stay length | Typical sash dimension* |
|---|---|
| 8 in (≈ 200 mm) | Up to about 400 mm |

| Lock or handle | Window | Specification |
|---|---|---|
| Crescent lock | Sliding windows | Fits the meeting rails; aluminum, chrome or black |
| Sliding window lock handle | Sliding windows | Combined pull and lock |
| Flush handle | Sliding windows | Aluminum, for 30–60 mm sash frames |
| Casement window handle | Casement and top-hung | Aluminum or zinc alloy, 40–70 mm frames |

| Multi-point lock rods | Large casements, high-rise | Several locking points along the sash |
See the crescent window lock guide and the door and window lock range.
Most sliding window sashes run on two rollers, one near each end of the bottom rail. Window rollers usually have nylon or POM wheels with a small ZZ bearing for quiet running, in nylon or steel brackets shaped to the profile cavity. Typical sashes weigh 20–40 kg; heavier sashes need double-wheel rollers.
Match the wheel groove to the track and the bracket to the sash cavity. Our sliding door and window roller guide explains wheel materials, bearings and load step by step.
Corner joints are inserts that join two mitred profiles at each corner of a frame or sash. They keep the window square, carry load across the corner and make assembly fast and repeatable.
| Type | Fixing | Material |
|---|---|---|
| Standard corner joint | Screw or press-fit (crimped) | Aluminum, zinc alloy |
| Corner bracket | Screw fixing, L-shape | Zinc alloy, steel |
| Angle bracket | Screw fixing, heavy-duty | Steel, alloy |
| Internal connector | Hidden in the profile | To your profile |
HIPAD corner joints such as HDJ02 and HDJ37 fit the most common international aluminum window systems. Standard MOQ for corner joints is 10,000 pcs.

| Problem | Likely cause | Fix |
|---|---|---|
| Sash drops or rubs the frame | Stay too short or worn | Use a longer or heavy-duty stay |

| Rusty stays | 201 or 410 in a wet climate | Change to SS304 |
| Sliding sash hard to move | Worn rollers or dirty track | Clean the track; replace rollers |
| Lock does not pull the sash closed | Keeper out of position | Reset the keeper; check sash alignment |
| Draughts and noise | Worn or wrong weatherstrip | Replace with the correct profile |
HIPAD started in 2000 with bearings and rollers and grew into a full door and window hardware factory. Friction stays, locks, handles, rollers and corner joints are produced and checked under one quality system, so a window factory can source a complete, matched hardware set from one supplier.
HIPAD is ISO 9001 certified, and applicable products carry CE, GS and CSA C-UL certification. SGS or BV third-party inspection is available.

An opening aluminum window needs friction stays or hinges (or rollers for sliding windows), a handle, a lock or crescent lock with keepers, four corner joints per sash and weatherstrips. Restrictors and multi-point locks are added for safety and large sashes.
A friction stay is a folding stainless steel arm fitted in the frame and sash of a casement or top-hung window. It carries the sash, guides it as it opens and holds it at any angle by friction, replacing ordinary hinges.
Choose the stay length by sash width for side-hung windows and by sash height for top-hung windows. As a guide, 10 in stays suit sashes of about 400–500 mm and 16 in stays about 550–750 mm. Heavy sashes need heavy-duty or 5-bar stays. HIPAD makes stays from 8 to 24 in.
SS304 stainless steel is best for humid, coastal and high-rise projects because it resists rust. SS201 suits dry inland projects at lower cost, and SS410 is a hard, economical choice for sheltered windows.
A 5-bar stay has an extra arm that supports heavier sashes and keeps them more stable when open. 4-bar stays suit standard sashes.
Most aluminum sliding windows use a crescent lock on the meeting rails, a lock handle that combines pull and lock, or a keyed window lock for extra security.
