Custom Quartz Brackets, Supports & Holders
| Parameter | Typical Range |
|---|---|
| Overall size | Confirmed per equipment envelope |
| Mounting holes | Mechanical/diamond drilled ≥Ø0.8 mm, ±0.02 mm |
| Support-point position tolerance | ±0.05–0.1 mm |
| Rod / plate stock size | Confirmed per structure |
| Welded joints | Confirmed per assembly |
| Assembly flatness / distortion | Confirmed per order |





Quartz brackets and support structures machined and welded to your mounting-hole layout and support-point positions — built around how the part actually mounts in your equipment.
Overall size, mounting-hole position, and support-point position are one layout, not independent dimensions — a hole or support point positioned relative to the wrong reference edge won't align once the bracket is installed. Send a full drawing with a stated datum, not individual hole positions.
Common Quartz Support and Holder Structures
Brackets, stands, and holders are built from rod and plate stock combined by welding — a plate base with welded rod supports, or a rod frame with machined mounting features, depending on what the structure needs to hold and how it mounts. Tell us what the bracket supports (a tube, a plate, a component) and how it attaches to your equipment.
Mounting Holes, Support Points and Welded Joints
Mounting holes are added by mechanical or diamond drilling down to about Ø0.8 mm at ±0.02 mm; larger holes or slots are CNC-machined. Support points — where the structure contacts whatever it's holding — are positioned to match your component's geometry, not placed generically. Welded joints between rod and plate sections are checked for both strength and position, since a joint that's structurally sound but slightly misaligned can still throw off the overall support geometry.
Before shipment we check overall dimensions, hole/slot position, support-point position, straightness/flatness of the assembly, weld condition, and fit against your equipment drawing where provided.
Support Points and Mounting Features Matter More Than the Outside Envelope
| Controlled Feature | Reference Capability / Requirement |
|---|---|
| Structure | L-shaped, U-shaped, cage or platform geometry |
| Overall Size | Finished envelope matched to furnace or process equipment |
| Support Points | Contact locations dimensioned from assembly datums |
| Holes / Slots | Diameter, width and position defined only where functional |
| Welded Joints | Joint locations and allowable assembly distortion stated |
| Dimensional Reference | ±0.1 mm industry-reference level for general critical features |
| Edges | Chamfered, ground or fire-polished according to handling |
| Material | JGS2-class fused quartz option |
Choose the Structure Around Load and Access
| Structure | Function | Drawing Controls |
|---|---|---|
| L bracket | Two-plane locating or edge support | Legs, angle and holes |
| U support | Cradle around a tube or sample | Opening, height and contact points |
| Cage frame | Multi-point support with open access | Rails, joints and distortion |
| Platform | Flat sample or component support | Plane, holes and mounting height |
