Aluminum sliding patio doors fitted with HIPAD sliding door hardware

What Is Sliding Door Hardware?

A sliding door moves along a track instead of swinging on hinges. Its hardware splits into four jobs. Carry and move: rollers, tracks, top guides and stoppers. Close and seal: interlock profiles, brush seals and weatherstrips. Lock and operate: sliding door locks, keepers and handles. Hold the frame together: corner joints and connectors in the aluminum profile.

The same names cover very different doors: a heavy aluminum patio door rolling on a sill track, a wooden or glass door hanging from an overhead rail, a wardrobe door, or a synchronized interior door where two panels open together. The right hardware depends on the door system, panel weight and frequency of use. In Spanish the parts are often called herrajes para puertas corredizas oppure accesorios para puertas corredizas, and rollers roldanas.

Step 1 · Door system

Types of Sliding Door Systems and the Hardware Each Needs

Risposta breve: bottom-rolling aluminum patio doors need rollers, a sill track, a hook lock and a flush handle; top-hung interior, barn-style and glass doors need hanging rollers on an overhead rail with a floor guide; wardrobes use light bypass rollers; and synchronized doors add a belt or cable that moves two panels together.

Sistema	How it works	Key hardware	Uso tipico	HIPAD supply
Bottom-rolling aluminum door	Panel rolls on rollers in the bottom rail along a sill track	Tandem or embedded rollers, top guide, hook lock, flush handle, corner joints, brush seals	Patio and balcony doors, shop fronts	Complete hardware set

Featured system

Sistema di porte scorrevoli sincronizzate Short Track 2+1

In a synchronized sliding system, pulling one door panel moves the linked panel at the same time, so a wide opening clears in one movement. The HIPAD Short Track 2+1 system uses a belt drive on a short, low track, which keeps the visible hardware small. A buffer at each end slows the doors over the last 70 mm so they close softly.

Sliding structure	Belt-driven synchronized sliding
Door weight	35–100 kg
Buffer stroke	70 mm
Minimum door leaf	≥ 520 mm wide
Service life (stated)	80,000 cycles
Materials	Metal and engineering plastic
Uses	Interior doors, wardrobes, commercial partitions

See the 2+1 specification guide for what to confirm before ordering.

Step 2 · Lock and handle

Sliding Door Locks and Handles: How to Choose

A sliding door lock usually uses a hook that swings into a keeper on the frame, because a sliding panel cannot use a normal latch bolt. Choose the lock by door thickness and profile, then choose a handle that fits the lock spindle and the profile face.

Typical HIPAD lock ranges; see door and window locks.
Lock type	Use	Door / frame	Materiale
Sliding door hook lock	Porte scorrevoli in alluminio	30–60 mm doors	Lega di zinco
Mortise lock	Aluminum doors with lever handles	35–70 mm doors	Steel and zinc alloy
Crescent lock	Finestre scorrevoli	Window frame systems	Alluminio
Multi-point lock	Entrance and large doors	40–80 mm doors	Steel core

Handles in aluminum and zinc alloy, anodized, powder coated or plated; see custom handle sets.
Handle type	Use	Cornice
Flush (recessed) handle	Sliding windows and doors, panels that pass each other	30-60 mm
Lock handle	Sliding windows and light doors	Profile-specific
Lever handle with lock	Aluminum doors with mortise lock	35–60 mm
Pull handle	Glass and timber sliding doors	Through-fixed or face-fixed

Step 3 · Door weight

Match the Hardware to the Door Weight

Door weight drives the roller choice and affects the track, lock and handle. Estimate it first: glass weighs about 2,5 kg per m² per millimetro, and an aluminum frame adds roughly 20–30%. A 1000 × 2200 mm sash with 5 + 5 mm double glazing weighs about 69 kg.

Choose rollers rated for at least 1.5 times the weight each roller carries. Our roller load guide explains the calculation step by step.

Typical planning ranges. The rated load of each HIPAD model is confirmed against your drawing.
Panel weight	Typical hardware
Up to 40 kg	Window rollers, wardrobe rollers, light top-hung rollers
35–100 kg	2+1 synchronized system for interior doors
40–80 kg	Single-wheel door rollers with bearings
80–150 kg	Tandem or embedded rollers, heavier track
Above 120 kg	Roller strips with 4–8 wheels or steel-wheel heavy-duty rollers

Sliding Door Hardware FAQ

What hardware is needed for a sliding door?

A sliding door needs rollers and a track to carry and move the panel, top guides and stoppers, a lock with a keeper, a handle, and seals at the interlock and around the frame. Aluminum sliding doors also need corner joints to assemble the sash.

What is the difference between top-hung and bottom-rolling sliding doors?

In a bottom-rolling door the weight sits on rollers in the bottom rail that run on a floor or sill track, which suits heavy aluminum patio doors. In a top-hung door the weight hangs from rollers on an overhead track and a floor guide only keeps the door in line, which suits interior, barn-style and glass doors.

How does a synchronized sliding door work?

A belt or cable links the panels, so pulling one panel moves the other at the same time and the opening clears in one movement. The HIPAD Short Track 2+1 system is belt-driven, carries doors of 35–100 kg and has a 70 mm soft-stop buffer.

What kind of lock is used on an aluminum sliding door?

Most aluminum sliding doors use a hook lock that swings into a keeper on the frame. HIPAD sliding door locks fit doors 30–60 mm thick and come with or without a key cylinder.

How do I choose rollers for a sliding door?

Estimate the panel weight, divide it between the rollers and choose rollers rated for at least 1.5 times that share. Then match the wheel groove to the track and the housing to the profile cavity. Our sliding door roller guide explains each step.

Can you supply a complete hardware set for our profile system?

Yes. Send the profile drawing or a sample door. We match rollers, guides, locks, handles, corner joints and seals to it and can pack them as one kit per door or in bulk.

Which materials are best for sliding door hardware near the sea?

Use stainless steel roller housings, sealed (RS) bearings and plated or powder-coated locks and handles. Plain zinc-plated steel corrodes faster in coastal and pool areas.

What is the MOQ and lead time?

MOQ starts from 1000 pcs and depends on the model. Samples of existing models take 5–7 days and mass production 20–25 working days. Logo and packaging customization is available even for small quantities.

Is HIPAD a manufacturer or a trading company?

HIPAD is a manufacturer founded in 2000 in Qingdao, China, starting with bearings and rollers and now producing complete sliding hardware with its own molds and injection machines. HIPAD is ISO 9001 certified. Qingdao Hipad International Trade Co., Ltd. handles export.
