Roll- Up Ser­randa’s spe­cialised roller shut­ters for spe­cial projects

The Mercury - - BUSINESSREPORT -

Roll-Up Ser­randa is well known in KwaZulu-Natal for its roller shut­ters fronting re­tail out­lets in shop­ping cen­tres, pro­tect­ing ware­houses from un­law­ful en­try, and even adding ex­tra se­cu­rity to homes. Less well known are their spe­cialised roller shut­ters, used to guard against more un­usual dan­gers such as lethal gases or Àre. “Our re­search and de­vel­op­ment is on­go­ing, and many of our spe­cialised prod­ucts are the re­sult of site-speciÀc re­quire­ments, re­quested by cus­tomers. Th­ese new de­vel­op­ments of­ten be­come a stan­dard part of our spe­cialised range,” said Rob Chivers, Roll-Up Ser­randa’s KZN Branch Man­ager. The re­sult has been that Roll-Up Ser­randa now has the most com­pre­hen­sive range of spe­cialised de­signs in the roller shut­ter in­dus­try. Some of th­ese unique prod­ucts in­clude: Fire rated roller shut­ters The Àrst of their kind in South Africa to be awarded in­ter­na­tional cer­tiÀ­ca­tion, Roll-Up Ser­randa s Àre rated doors are ideal for high risk applications. Th­ese roller shut­ters don’t re­quire elec­tric sen­sors or hy­draulic mech­a­nisms in the event of Àre. They op­er­ate with a fusible link and de­scent con­trol mech­a­nism, re­main­ing per­ma­nently open un­til au­to­mat­i­cally ac­ti­vated in case of Àre. They can be in­te­grated with ex­ist­ing Àre pro­tec­tion sys­tems. The Àre doors are avail­able in two size ranges and have been tested us­ing the ISO stan­dard time-tem­per­a­ture curve in ac­cor­dance with SABS re­quire­ments, reach­ing tem­per­a­tures of 1051°C. Both sizes are cer­tiÀed by TUV Rhein­land, a Ger­man based test­ing fa­cil­ity with in­ter­na­tional cred­i­bil­ity. High shut­ters Roll-Up Ser­randa has de­vel­oped pur­pose-de­signed roller shut­ters to safe­guard ATM s coun­try­wide. The re­quest was to de­velop roller shut­ters that could pro­vide a high level of se­cu­rity without hard­en­ing the bank’s brand and that was non-threat­en­ing to cus­tomers. They also had to com­ply with health and safety reg­u­la­tions. The units are ‘semi-in­tel­li­gent,’ open­ing and clos­ing au­to­mat­i­cally on a timer without hu­man in­ter­fer­ence. Tor­nado shut­ters Se­cu­rity is­sues may re­fer to weather con­di­tions rather than crim­i­nal at­tack. Shut­ters of over 30m² com­monly be­come ‘sails’ in high winds such as the Cape South­easter, and can blow out of their tracks if not cor­rectly de­signed.


wind Roll-Up Ser­randa was re­quested by an in­ter­na­tional bank sit­u­ated in a cy­clone zone as well Port Au­thor­i­ties around South Africa s coast­line to de­sign a roller shut­ter that could with­stand the se­vere buf­fet­ing of ex­ces­sive winds. Th­ese doors are now a per­ma­nent part of the Roll-Up Ser­randa range.




roller Man­u­fac­tured from ei­ther solid gal­vanised steel or alu­minium slats with a dou­ble wall cav­ity ex­tru­sion, they are ex­tremely ro­bust. Steel roller shut­ters can with­stand wind speeds of up to 120km/hour while alu­minium ver­sions are suit­able for wind speeds of up to 200km/hour. Petrol bomb re­sis­tant leak proof roller shut­ters Th­ese doors were de­vel­oped for an in­sti­tu­tion that re­quired pro­tec­tion against both gas leaks and bomb at­tacks as they are in an area plagued by ‘Molo­tov Cock­tail’ bomb­ings. Four of th­ese roller shut­ters were Àt­ted to the in­sti­tu­tion s head ofÀce. They are highly suit­able for em­bassies, gov­ern­ment build­ings, art and arte­fact gal­leries and mu­se­ums. Man­u­fac­tured from alu­minium, th­ese



dou­ble wall roller shut­ters will seal an area against gas leaks, pre­vent gases from spread­ing into or out of a build­ing and are ca­pa­ble of with­stand­ing the force of a high im­pact petrol bomb at­tack. They have been tested ac­cord­ing to SABS stan­dards. “We li­aise closely with our clients from the plan­ning stage of their project through to de­sign, in­stal­la­tion and af­ter sales ser­vice,” said Rob. “Our Pine­town team is highly ex­pe­ri­enced and al­ways avail­able to dis­cuss the most ap­pro­pri­ate roller shut­ter for the site, which could in­clude a mix of our com­mod­ity roller shut­ters and spe­cialised de­signs.”
