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 ou accesorios para puertas corredizas, and rollers roldanas.

Step 1 · Door system

Types of Sliding Door Systems and the Hardware Each Needs

Réponse rapide : 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.

Système	Comment ça marche	Key hardware	Utilisation courante	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
Sliding window	Same as above at a smaller scale	Window rollers, crescent or hook lock, lock handle, corner joints	Aluminum and uPVC windows	Complete hardware set; see Quincaillerie de fenêtre
Top-hung interior door	Door hangs from rollers on an overhead track	Hanging rollers, top track, floor guide, stoppers, soft-close	Interior rooms, pocket doors	Hanging rollers and roller systems
Synchronized (2+1)	A belt links the panels so they open together	Short track, carriages, belt, buffers	Interior doors, wardrobes, partitions	Complete 2+1 system
Wardrobe bypass door	Two or more doors pass each other on parallel tracks	Light top or bottom rollers, guides	Closets and cabinets	Wardrobe rollers
Frameless glass sliding door	Glass hangs from rollers on a rail or tube	Glass clamp rollers, rail, stoppers, floor guide, pull handle	Showers, glass partitions, barn-style glass doors	Sliding glass systems

Featured system

Système de portes coulissantes synchronisées 2+1 à rail court

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	Matériel
Sliding door hook lock	Portes coulissantes en aluminium	30–60 mm doors	Alliage de zinc
Mortise lock	Aluminum doors with lever handles	35–70 mm doors	Steel and zinc alloy
Crescent lock	Fenêtres coulissantes	Window frame systems	Aluminium
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	Cadre
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 à 60 mm
Pull handle	Glass and timber sliding doors	Through-fixed or face-fixed

Étape 3 · Poids de la porte

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 par m² par millimètre, 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

Quelle quincaillerie faut-il pour une porte coulissante ?

Une porte coulissante nécessite des roulettes et un rail pour supporter et déplacer le panneau, des guides supérieurs et des butées, une serrure avec gâche, une poignée, ainsi que des joints au niveau du montant de recouvrement et autour du cadre. Les portes coulissantes en aluminium nécessitent également des équerres d’assemblage pour monter l’ouvrant.

Quelle est la différence entre les portes coulissantes suspendues et à roulement inférieur ?

Dans une porte à roulement inférieur, le poids repose sur des galets situés dans le rail inférieur, qui roulent sur un rail de sol ou de seuil ; cette solution convient aux lourdes portes-fenêtres en aluminium. Dans une porte suspendue, le poids est supporté par des galets sur un rail supérieur et un guide au sol maintient uniquement la porte alignée ; cette solution convient aux portes intérieures, de style grange et en verre.

Comment fonctionne une porte coulissante synchronisée ?

Une courroie ou un câble relie les panneaux ; ainsi, tirer un panneau déplace l’autre en même temps et l’ouverture se dégage en un seul mouvement. Le système HIPAD Short Track 2+1 est entraîné par courroie, supporte des portes de 35 à 100 kg et dispose d’un amortisseur à fermeture douce de 70 mm.

Quel type de serrure utilise-t-on pour une porte coulissante en aluminium ?

La plupart des portes coulissantes en aluminium utilisent une serrure à crochet qui s'engage dans une gâche sur le cadre. Les serrures pour portes coulissantes HIPAD conviennent aux portes de 30 à 60 mm d'épaisseur et sont disponibles avec ou sans cylindre à clé.

Comment choisir des roulettes pour une porte coulissante ?

Estimez le poids du panneau, répartissez-le entre les roulettes et choisissez des roulettes prévues pour au moins 1,5 fois cette charge. Faites ensuite correspondre la gorge de la roue au rail et le boîtier à la cavité du profilé. Notre guide des roulettes pour portes coulissantes explique chaque étape.

Pouvez-vous fournir un ensemble complet de quincaillerie pour notre système de profilés ?

Oui. Envoyez le dessin du profilé ou un échantillon de porte. Nous y adaptons les roulettes, guides, serrures, poignées, équerres d’assemblage et joints, et pouvons les emballer en un kit par porte ou en vrac.

Quels matériaux sont les plus adaptés pour la quincaillerie de portes coulissantes près de la mer ?

Utilisez des boîtiers de roulettes en acier inoxydable, des roulements étanches (RS) et des serrures et poignées plaquées ou thermolaquées. L’acier simplement zingué se corrode plus rapidement dans les zones côtières et autour des piscines.

Quelle est la MOQ et quel est le délai de livraison ?

La MOQ commence à 1 000 pièces et dépend du modèle. Les échantillons de modèles existants nécessitent 5 à 7 jours et la production de masse 20 à 25 jours ouvrables. La personnalisation du logo et de l’emballage est possible même pour de petites quantités.

HIPAD est-il un fabricant ou une société de négoce ?

HIPAD est un fabricant fondé en 2000 à Qingdao, en Chine. L’entreprise a débuté avec les roulements et les roulettes et produit désormais une quincaillerie coulissante complète grâce à ses propres moules et machines d’injection. HIPAD est certifiée ISO 9001. Qingdao Hipad International Trade Co., Ltd. gère l’exportation.
