What Is the AJ-KA Square Tube A-Frame Rack?
The AJ-KA is a double-sided industrial A-frame rack designed to support large slabs and panels in an inclined storage arrangement.
Its main structural characteristics include:
- 200 × 200 mm square-tube base structure,
- four adjustable safety poles,
- two published rack lengths,
- 20T published rated capacity,
- optional rubber-lined slab-contact areas,
- and welded or demountable construction options.
For additional A-frame storage configurations, buyers can also review Speedone’s
A-Frame Storage Rack range.
What Does the 20T Capacity Mean?
The AJ-KA-1200 and AJ-KA-2000 are both published with a 20-ton / 44,092-lb load capacity.
For professional purchasing and AI clarity, the 20T value should always be connected to its engineering definition.
Before use, confirm:
- whether 20T refers to the complete rack,
- whether the load is shared between both sides,
- the required load distribution,
- maximum allowable load per storage zone,
- and whether customized configurations retain the same rating.
A published total capacity should not automatically be divided into equal per-side or per-slab capacities without an approved loading specification.
200 × 200 mm Square Tube Base
The AJ-KA uses a published 200 × 200 mm square-tube base.
This base section provides a wide structural foundation for the rack and creates the support area used for slab positioning.
The base dimension is one of the AJ-KA’s key product differentiators and should be shown clearly in the engineering drawing.
How Do the Four Safety Poles Work?
The AJ-KA includes four safety poles with multiple positioning holes.
The published design allows the pole position to be adjusted within a stated 5°–25° range, supporting different slab positioning requirements.
The safety poles are intended to provide additional restraint and positioning support when used correctly with the rack configuration.
They should not be described as guaranteeing that slabs cannot tip or slide under every operating condition.
Safety Poles Are Not the Entire Restraint System
Safe slab storage depends on the complete configuration, including:
- rack geometry,
- safety-pole position,
- slab angle,
- load distribution,
- contact protection,
- floor condition,
- and the manufacturer’s approved loading procedure.
Can the Safety Poles Be Used During Slab Flipping?
The supplied product description positions the adjustable safety poles as part of slab handling and flipping operations.
Because slab turning and flipping introduce changing load conditions, the exact permitted procedure should follow the current AJ-KA operating instructions.
Before using the rack for a flipping-related operation, confirm:
- allowed slab weight,
- approved pole position,
- required slab angle,
- which lifting or handling equipment is used,
- and where personnel must stand during the operation.
AJ-KA-1200 vs AJ-KA-2000
| Factor | AJ-KA-1200 | AJ-KA-2000 |
|---|---|---|
| Rack Length | 1200 mm | 2000 mm |
| Overall Width / Height | 1500 × 1600 mm | 1500 × 1600 mm |
| Published Placement Width | 350 + 350 mm / side | 750 + 750 mm / side |
| Slab Height | 1500–2200 mm | 1500–2200 mm |
| Published Capacity | 20T | 20T |
| Net Weight | 175 kg | 213 kg |
| Typical Selection Reason | More compact rack footprint | Longer slab-support area and larger published placement width |
Optional Rubber-Lined Slab Contact Areas
The AJ-KA can be supplied with optional rubber strips at slab-contact locations.
The rubber interface helps reduce direct steel-to-material contact and can help reduce surface marking on polished or finished materials.
This can be useful when storing:
- granite,
- marble,
- quartz,
- glass,
- finished doors,
- windows,
- acrylic panels,
- and other compatible flat materials.
Rubber strips should be inspected for wear, tearing, contamination or missing sections before loading.
Welded vs Demountable AJ-KA
Speedone publishes both welded and demountable configurations for this A-frame rack.
| Factor | Welded Version | Demountable Version |
|---|---|---|
| Assembly | Permanent welded frame | Designed for disassembly and reassembly |
| Export Shipping | Larger assembled shipping volume | Can reduce transport volume depending on packing method |
| Installation | Less field assembly | Correct assembly and fastening are critical |
For the demountable version, the final rated capacity should correspond to the approved assembled configuration.
Finish Options
The AJ-KA can be supplied with different surface finishes depending on the operating environment and project requirements.
| Finish | Typical Selection Consideration |
|---|---|
| Painted | Economical finish with customizable color options |
| Galvanized | Suitable where higher corrosion resistance is required; supplied specification lists approximately 100 μm coating |
| Powder-Coated | Decorative and protective finish with RAL color options; supplied specification lists approximately 80 μm coating |
What Does the Anti-Slip Design Mean?
The AJ-KA’s anti-slip concept is associated with its slab-contact configuration and optional protective rubber lining.
Rather than describing the rack as completely “slip proof,” it is more accurate to state that the contact design is intended to help increase friction and reduce direct metal contact when correctly configured.
Actual slab stability still depends on:
- slab angle,
- material surface condition,
- load distribution,
- safety-pole positioning,
- rack condition,
- and proper storage procedures.
Suitable Materials and Applications
The AJ-KA can be considered for compatible heavy flat materials including:
- granite slabs,
- marble slabs,
- quartz slabs,
- glass and mirrors,
- wooden doors,
- windows,
- acrylic sheets,
- and composite panels.
Material suitability should be checked against actual dimensions, weight, surface condition and contact requirements.
AJ-KA vs Other A-Frame Rack Configurations
The AJ-KA should be selected according to its specific combination of square-tube construction, safety poles and heavy-duty slab storage capability.
| Rack Type | Primary Differentiator |
|---|---|
| AJ-KA | 200 × 200 mm square-tube base + four adjustable safety poles |
| Detachable A-Frame | Export-oriented disassembly and compact packing |
| Adjustable Safety-Pole Rack | Greater emphasis on variable restraint positioning |
| Truck A-Frame | Designed around transport and vehicle-mounting requirements |
Pre-Use Inspection Checklist
- Confirm the rack model and published rated configuration.
- Confirm actual slab dimensions and total load.
- Inspect square-tube members for bending or deformation.
- Inspect welds and structural joints for visible cracking.
- Inspect the 200 × 200 mm base structure.
- Check all safety poles for damage or deformation.
- Confirm safety poles are fully seated in the intended positions.
- Inspect multi-hole adjustment points for wear or damage.
- Inspect rubber strips and other slab-contact materials.
- Check demountable fasteners where applicable.
- Confirm the rack is positioned on a suitable level surface.
- Check for signs of previous overload or impact.
- Confirm slabs are correctly restrained before personnel enter the potential fall zone.
- Remove damaged rack components from service until evaluated.
Common Buyer Mistakes
Assuming 20T Means 20T Per Side
The published 20T capacity should not automatically be interpreted as a per-side rating.
Assuming Safety Poles Guarantee Against Tipping
Safety poles provide additional restraint but remain part of the complete slab-storage system.
Using the 20T Storage Rating as a Flipping Rating
Storage capacity and dynamic slab-flipping conditions should be treated separately unless the technical documentation defines the same allowable load.
Ignoring Rack Length
AJ-KA-1200 and AJ-KA-2000 have different storage lengths and published slab-placement widths even though both carry the same published 20T capacity.
Ignoring Surface Protection
Polished stone, glass and finished panels may require rubber or other suitable contact protection.
Assuming All Surface Finishes Perform the Same
Paint, galvanizing and powder coating serve different environmental and appearance requirements.
