Glass Panels---
Glass hood for museum display cases of table design is made by 3-ply laminated safety glass which meets BS EN356 Part 4A,the international authoritative criteria of safety glass.Optiwhite glass with low iron content or ultra clear glass with low reflective coat ensures high light transmittance with no vision distortion.All glass frameless construction and invisible glass bonding bring no any sight obstruction on display.UV bonding adhesive under advanced UV bonding technology and dedicated cure agent make glass hood and drawer cases elegant but solid.Specifications of glass like 4+0.76+4,5+0.76+5,4+1.52+4,5+1.52+5 for usual option.
Construction Support---
For museum display cases of table design,the metal profile to receive glass panels is made by dedicated powder-coated aluminum extrusions and then is tightly secured to lower steel structure.Lower steel table structure to support upper part is made of mild/low carbon steel in powder-coating finish.Each drawer unit is mounted on the dedicated heavy-duty sliding system.Levelling adjusters and master rollers at the feet get table display case more convenient and practical.
Inner Invironment---
As inert materials are comprehensively applied for making museum display cases of table design,no any chemical reaction will take place inside internal environment of cases.All the adhesive,sealant and cure agent for bonding are completely neutral and non-hazardous,and that ZF-MDF panel for dressing baseboard is fully sealed by aluminized polyethylene film then veneered with environmental fabric,so internally,no destructive pollutional VOCs will bring any damage on displayed exhibits including sensitive artifacts.
Shelving System---
For table display cases with drawer or storage cabinets, usually fabric-dressed ZF-MDF baseboards work as shelving platform.

Opening solution for glass hood is swing opening for partial access and pull & push opening for individual drawer units.For easy and secure operation,swing opening is usually additionally supported by 2 gas strut from sides.For easy operation,each drawer can fix a handle.
Air Tightness---
Consistency of structure by dedicated extrusions,precise fabrication on glass and metal parts work together with seal extrusion,seal sealant and silicon seal strip to create a well airtightness at a minimal air exchange rate not more than 0.2 every 24 hours,consequently,a dust-proof internal display space is created.
Microclimate Control---
To reach a relatively constant humidity and temperature for perfect conservation on displayed exhibits,museum table display cases of drawer design are discretely and invisibly equipped with passive microclimate control systems.Passive microclimate control system is usually realized by silicon gel/artsorb/prosorb inside the dedicated metal tray under baseboards.
Lighting System---
